However, this statement | makes me wonder if it is meant to run their backend hardware and | not consumer products. | qmarchi wrote: | Actually quite the opposite, Fuchsia already runs on production | devices manufactured by Google. The (ridiculously long named) | Google Nest Home Hub and Home Hub Max both can run Zircon and | Fuchsia on device, although it's very much for development. | skavi wrote: | There's a fairly heavy emphasis on graphics and UI throughout | Fuchsia's stack, so I doubt it's meant to just sit on a server. | [deleted] | [deleted] | tarkin2 wrote: | I have mixed feelings. This brings invitation to the operating | system world. But it will track user behaviour from its core. | catern wrote: | >Fuchsia aims to provide drivers with a binary-stable interface. | In the future, drivers compiled for one version of Fuchsia will | continue to work in future versions of Fuchsia without needing to | be modified or even recompiled. This approach means that Fuchsia | devices will be able to update to newer versions of Fuchsia | seamlessly while keeping their existing drivers. | | This is a massive step back for open source. The fact that Linux | doesn't have a binary-compatible driver interface is a good | thing: It means hardware vendors have a very strong incentive to | get their drivers upstream into the kernel. And indeed, on | servers and laptops and desktop machines, this has largely | happened. But on mobile platforms, with Android, it has not | happened. For various reasons, but nothing fundamental. | | We would all benefit if Android hardware drivers were upstreamed. | This would allow for a much more competitive, and higher quality, | software and hardware ecosystem on mobile platforms. | | But Fuschia is going in the exact opposite direction: It makes it | possible to build proprietary drivers. It's for this reason that | I hope Fuschia is not successful. We already have a high quality | kernel: Linux. If Fuschia is "not a science experiment", but | instead intended to use proven ideas, then any improvement that | could be added to Fuschia could be added to Linux. We don't need | a new operating system whose only advantage is that it's easier | to write proprietary drivers. | ReactiveJelly wrote: | It's a negotiation, and the hardware vendors seem to be 100% | happy stepping away from the table and letting old hardware | suffer. | | They have a lot more leverage than we FOSS supporters do. | netdur wrote: | sorry but that's just naive idealism, my wife has android | flagship, a Samsung s10, she will receive one more year of | updates, then she will be on her own, my daughter has iPhone | 6S, this old device will receive iOS 14 soon. | | my wife do not care about updates, she will not hesitate a | second to get iPhone once she knows her social media or | pictures is not safe on her android device, this is the issue | Android have and Fuchsia have to fix. | ptomato wrote: | > For various reasons, but nothing fundamental. | | "Hardware vendors being unwilling to make the drivers they | write open source" is a pretty fundamental reason. | | Which is worse, a phone where you can't update kernel because | of the closed drivers or a phone where you can update the | kernel, with closed drivers? I don't think that realistically | there's a third option. The open source community is not, for | example, going to make their own high performance gpus. | snazz wrote: | Plus, better isolation between driver code and other kernel | code (which Fuchsia seems to bring; correct me if I'm wrong) | would be good for everyone, since you can be relatively | assured that running vendor-provided driver blobs is safe. | zozbot234 wrote: | "Isolation" of driver code that can talk to on-SoC hardware | is just not very meaningful. You can only have real driver | isolation if it's enforced on the hardware side via some | IOMMU mechanism (or by keeping the hardware isolated on the | USB bus, etc.), otherwise you're just adding pointless | overhead for no real benefit. | cycloptic wrote: | I would not say that is a fundamental reason. They have been | willing to do it when the proper incentives are there. The | incentive to keeping it closed source is primarily part of a | strategy to sabotage their competitors, which I hope is not a | behavior that anyone here is complicit in. Please don't work | for hardware companies that do this, there are plenty of | companies out there that know how to spend their money in | other ways. | | >Which is worse, a phone where you can't update kernel | because of the closed drivers or a phone where you can update | the kernel, with closed drivers? | | Neither of those are good options because even in the second | case, there are still vast swaths of code that upstream is | not going to touch out of fear of breaking things, the end | result being that you still get stuck with unfixable kernel | and driver bugs. | | >The open source community is not, for example, going to make | their own high performance gpus. | | The open source community includes a lot of companies. The | high-performance GPU companies are welcome to join this | community any time they like. | CJefferson wrote: | While I understand why you want open source drivers, the | situation hasnt improved for 10 years, and this is one of the | major reasons many phones end up not getting Android updates, | which makes Google/Android look bad. | est31 wrote: | > the situation hasnt improved for 10 years | | But it has. | | * I remember having major issues with printer drivers on | Linux 10 years ago. Nowadays thanks to IPP support I don't | need any drivers any more.

My reasoning is that, | presuming it succeeds technically, it could only be killed | politically if both Android and ChromeOS prevented Fuchsia | from being used on first party devices.

If you submit code, you grant a license to | Google to use it in non-proprietary code.[1] So, at some point, | once users and developers are locked in, Google can make later | versions closed and proprietary enough to stop clones. | | Like they did to Android with Google Play Services. | | [1] https://cla.developers.google.com/about/google-individual | rstat1 wrote: | Google Play Services was never open. You can however still | submit changes to the actual OS though. | | People said the same thing about Android in its early days. | It was wrong then, still wrong now, and will likely be just | as wrong in the future. | kick wrote: | 'Animats didn't claim they _were_ ever open. | | His claim was more along the lines of: Google Play Services | has over time subsumed more and more of core functionality, | enough to stop the creation of clones. | | Which is true. | joshuamorton wrote: | That's not what he claimed. He claimed that | | 1. Code submitted by third parties to android 2. was | moved into Google Play Services 3. And this was possible | only due to the CLA. | | This isn't true for a couple of reasons. 2 is | unsubstantiated (it's possible this is true, but I don't | think it is). Functionality certainly moved, but I don't | think there's reason to believe that code was copied. | | 3 just isn't true. Android is Apache licensed, so code in | android can be reused in proprietary code without a CLA. | What you can't do is relicense Android without a CLA. | Another user mentions that the Fuschia CLA doesn't allow | relicensing anyway, but I'm not an expert and don't have | knowledge of that. | smnrchrds wrote: | Once upon a time, Android had a mail client that was part | of the open source components. There was also GMail app | that was closed source. Then a couple of versions later, | the open source email app was discontinued and its | functionality was incorporated into GMail. And the same | thing has happened to many more apps and functionalities. | zozbot234 wrote: | The F-Droid store provides compelling alternatives to | essentially all of the old AOSP apps. (LineageOS also | maintains varieties of them.) The one component where | there's been a real issue for FLOSS apps is support for | centralized push notifications, and that's reliant on | 3rd-party services so "open" is not a very meaningful | characterization anyway. | snazz wrote: | Part of that has more to do with the fact that AOSP is | not used nearly as much and updating the default AOSP | apps is not a good use of time for Google. The AOSP | browser was never [edit: not recently] competitive with | Chrome and the AOSP mail app was never [edit: not | recently] competitive with Gmail. | kllrnohj wrote: | > The AOSP browser was never competitive with Chrome | | That's really not true, and not how it worked. Chrome was | _very_ late to the mobile game (first released 2012, a | year after Android 4.0 / ICS was released) and its first | few attempts on Android sucked. It was incredibly slow & | laggy when it first finally came to Android. | | It's obviously not a good use of resources to make _two_ | webkit-based browsers both targeting the same market, but | it was a complete swap out from one to the other over a | relatively short time-frame. It 's not like the mail vs. | gmail situation where it was actually two "competing" | apps for quite a long while. | nradov wrote: | Yes if no one puts time into updating the default AOSP | apps then they will stop being competitive. That seems | like a tautology. | 101404 wrote: | So basically you'd work for free for one of the wealthiest | companies. | | That's f'ed up. | cycloptic wrote: | It's not because you're also asking the same of them. If | you're submitting code upstream, you're essentially asking | the maintainers to perform code review and start | maintaining your contributions, for free. | plerpin wrote: | Uh, that's how the BSD and Apache licenses work. | magicalist wrote: | > _Not really open_ | | Not many people still consider non-copyleft open source | licenses not "open" (even the FSF disagrees on the need for | copyleft to be considered libre) and MIT, BSD, and Apache 2.0 | in particular are widely considered proper open source, so I | think you just mean "Not really copyleft", which, sure. | wmf wrote: | All permissively-licensed (MIT/BSD/Apache) code has that | property. If you contribute to BSD anyone can create a | proprietary derivative. | on_and_off wrote: | agree on the issue but I don't think that Play Services is a | great exemple. | | It has always been closed source and can be replaced in any | AOSP build.

In any case, Apache/BSD/MIT licensed | code can _already_ be used in proprietary code, the CLA does | not change that. | | The Google ICLA you cited [1] is basically the same as the | ASF ICLA [2]; the gist is that you retain copyright of your | contributions, you're not giving up your copyright -- i.e., | it's a copyright _license_ , not a copyright _assignment_ (as | some other CLAs are). | | And, naturally, _anyone_ can fork it if they wish, or | distribute proprietary, non-open-source versions of an Apache | /BSD/MIT-licensed project, subject to appropriate | attributions, if required, by the relevant licenses. | | However, neither you (nor Google) can claim copyright over | the entire project, because the copyrights are held by the | relevant contributors. Changing the license for the entire | project requires agreement from all copyright holders -- for | example, see what LLVM had to do when they chose to add a | clause to their license [3]. | | [1] https://cla.developers.google.com/about/google-individual | | [2] https://www.apache.org/licenses/icla.pdf | | [3] https://llvm.org/foundation/relicensing/ | ColanR wrote: | >> If you submit code, you grant a license to Google to use | it in non-proprietary [ _sic_ , I assume] code. | | > it's a copyright license, not a copyright assignment | | >> So, at some point, once users and developers are locked | in, Google can make later versions closed and proprietary | enough to stop clones. | | > you're welcome to fork it if you wish, or distribute | proprietary, non-open-source versions of the code | | It sounds like you're agreeing completely with everything | the parent said. | mbrukman wrote: | Sorry for not making it more clear; I was responding to | the statement: | | > _Not really open. If you submit code, you grant a | license to Google to use it in non-proprietary code.[1] | So, at some point, once users and developers are locked | in, Google can make later versions closed and proprietary | enough to stop clones._ | | The CLA does not change anything about the license, and | does not prevent or make it possible (or easier) to make | proprietary versions of the software (or your | contributions) -- all those conditions are in the license | itself, the CLA does not override or amend any terms of | the license. | | In other words, you can make the same argument about any | Apache, BSD, or MIT software, while the poster is | claiming that it's the CLA that enables making future | releases proprietary, which is why I pointed out that the | Google CLA is the same as the ASF CLA. | | If the argument is that Apache/BSD/MIT licenses are "not | really open" because they allow incorporating them into | proprietary software without releasing code, that's a | different argument and is really a distinction between | the "permissive" licenses like Apache/BSD/MIT and the | "copyleft" licenses like GPL, but again, that has nothing | to do with the CLA. | ColanR wrote: | That's a very fair point. Thanks for clarifying. | joking wrote: | The thing is that anyone can make that fork and use the | code on a proprietary system, not only google.

The | problem I've repeatedly experienced in Google open source | and as a Google Cloud customer (contract with Google FDEs | on-site) is that Googlers just don't listen.

The OP makes the point that Google | will find a way to use public contributions for Google's | own profit._ | | That's not the purpose of a CLA; that's the purpose of a | project's license. That was the point of my post. Anyone | can take a project with an Apache/BSD/MIT license | (whether or not the project has a CLA, it's orthogonal), | make a proprietary product from it, distribute it, sell | it, etc. and they would be just fine doing it, without | also sharing any of the source. | | To put it another way, a CLA cannot restrict proprietary | or commercial use of a patch or contribution, if the | underlying project license is Apache/BSD/MIT, because all | those licenses already allow commercial use, | incorporating software into proprietary / closed-source | products, etc. Such a CLA would be incompatible with the | project's license. | | I've never seen an Apache/BSD/MIT project where the _CLA_ | (and only the CLA) prohibits commercial / proprietary / | closed-source or any other use cases -- if you have an | example or two, could you please point them out? I'm very | curious to see how this would work in practice, because | this seems like a strong contradiction, so I would be | interested to see how this plays out in practice. | | [1] https://en.wikipedia.org/wiki/Proprietary_software | ColanR wrote: | They aren't disagreeing.
