I'm not sure I fully understand this.

Why are GrapheneOS releases dependant on Google releases?

They are dependent on the AOSP releases (which Google develops) and on the manufacturer updates (and because GrapheneOS runs on Pixels, then it goes back to Google again).

I can understand relying on an OEM to provide hardware support for a given model - but I'm finding it hard to understand why they're unable to continue supporting a release just because the upstream removes support for something.

I'm not even really sure what you mean by "manufacturer updates".

The more I hear about this project, the less is sounds like an alternative OS and more it sounds like a thin skin around whatever shit Google throws out, to be honest.

They rely on manufacturer support for device firmware, just like anyone else.

Debian surely doesn't depend on Lenovo or Asus to release OS updates for my laptop. Apparently it's not "everyone else" that needs this but it's some sort of dependency for mobile (qualcomm?) devices

I have trouble understanding why this is different on mobile devices. People keep speaking of blobs but that doesn't seem to be a thing in laptop/desktop hardware, unless they mean something like the firmware running on your wifi card and uefi chip? But those can be interfaced with from any kernel version, afaik, so I don't get it

Debian does not write the whole software stack running everywhere on your system. So if you want your system to be "supported", as in, "if a security flaw is discovered in a firmware, I want it patched and I want my firmware to be updated", then you need whoever writes that firmware to do it.

That's a dependency: if you want your system to be secure, you depend on the software running on your system to be patched when a security flaw is published.

Interesting, so any security patches to kernel level and above (AOSP code, browsers, other apps) can still be fully up-to-date when the manufacturer says a device is out of support. Not sure I understand the fuss then that Fairphone had about selecting a SoC with long support. Really thought it was some sort of problem updating the kernel or other AOSP components when using manufacturer blobs

The attack vectors against this firmware are virtually always physical right? As in, hardware access in one way or another (including radio waves reaching the device), not something that can be routed over a (cell) network

> why they're unable to continue supporting a release just because the upstream removes support for something.

If you have an EOL Pixel and a new major version of Android is released, Google will not port this new version of Android (and therefore AOSP) to it. So GrapheneOS would have to do it. GrapheneOS just say they don't have the resources to do that, so they follow the Google releases. Could you keep an EOL Pixel without receiving updates? Sure. But then it's not supported anymore, it's just outdated, insecure software.

> I'm not even really sure what you mean by "manufacturer updates".

There are the AOSP updates (which bring new features, but importantly in our case bring security fixes) that come from Google, but your phone is more than that. There is a bunch of hardware running in your phone and a bunch of firmwares exposing it. Say your camera, or your wifi module, etc. If there is a security issue in the firmware of the camera, then it won't be fixed in the AOSP codebase. You need the camera manufacturer to fix it and release a firmware, pass it to the phone manufacturer who will then deploy it on your phone.

Google split both of those concepts years ago in order to deploy Android updates faster and make everybody more secure, because manufacturers had a tendency to lag a lot. Some still do but the situation generally improved, I think. Anyway, you need to receive those security updates from your manufacturer because they are independent from Google.

If you think that AOSP is shit, then sure. I mean, if you think that the Linux kernel is shit, maybe you don't want to run a Linux distribution.

I personally think that AOSP is pretty great, and vastly superior to Linux on mobile (among other because it has a much better security model). I am not a big fan of Google being root on my phone (with Android and system apps like Play Services), which is something that GrapheneOS fixes (by making Play Services run like any other, unprivileged app). GrapheneOS is also adding privacy features, be it by proxying your location requests (so that they go through the GrapheneOS servers instead of directly to Google) or by adding features like "scopes", where you can choose exactly which contact you share with an app, for instance, or refuse Internet access to an app without breaking it (GrapheneOS will just make the app believe that it has the permission to access the internet but there is just no connection right now). And of course GrapheneOS hardens the system in terms of security (e.g. with a hardened malloc or memory tagging stuff that Apple recently introduced as well).

So yeah, it is relatively thin, because AOSP is a huge codebase. But it doesn't mean that it's worthless: this skin makes it more secure, more private, and for me more enjoyable than Android.

Sounds a bit disingenuous then for an article to have a title that includes the phrase "break free from Google".

I think they mean breaking free from Google Analytics, Google Play Services, Google Play, Google Location Services, etc. Play Services and Play are not installed on GrapheneOS by default, so it is possible to run your phone with just GrapheneOS with your choice of open/closed source apps on top.

I think breaking away from open source Google code is not really meaningful. It's kinda like saying "I don't want to run Linux because it contains code from IBM/Google/Meta". AOSP is a great and useful project. If the day that Google stops releasing AOSP ever comes, a consortium of interested organizations can fork it. But it does not make a whole lot of sense to start a new mobile ecosystem completely from scratch, if one that is great and open source already exists and buys you compatibility with millions of apps.

It was first "break free from Android", but somebody complained so they changed it. Titles are hard, I guess :-).
