Except you’re not forced to use the Play store if you’re using a non-Google fork of Android. So unless they’re locking out the entire OS if it doesn’t authenticate (which, if they do, that runs afoul of interoperability protections), you can still install APKs directly.
Also, if it’s at the silicon level, that’s not even in the OS, that’s in the device and Google is going to have to bet on device manufacturers (particularly Samsung, due to their market share) playing along. If Samsung in particular decides that Google is going too far (and they could, they have their own reputation to worry about and they’re also going to want to have control over the devices they make - control that Google could potentially deny them as they continue to tighten their grip), that’s game over. Google could try to push their own hardware but Samsung has too much market dominance in the mobile device hardware sector for Google to challenge like that.
They have already played along, all devices that have Google Play preinstalled have to pass this test.
But locking you out of installing software is not the point, it’s much more insidious than that. What will happen is that major services you rely on will want your device to present a cryptographic proof it’s running the original software, which can’t be spoofed. So for example your YouTube would only send you over the video stream if it knows that on the other side there’s an unmodified app running on an unmodified OS. Same thing goes for your bank. At some point you’re so locked out of essential services when running a custom OS that nobody will do it, because these days you almost need a phone to function in society.
The hardware doesn’t lock you out of your device, it lets remote servers present you with an ultimatum, if you don’t present the proof you’re out, if you do, that means you’re running the stock OS and thus can’t do anything.
So, in other words, I’ve been halucinating the fact that these services work perfectly fine on my Omnirom-patched OnePlus 7 Pro?
Nope! The point is that the hardware is deployed, and strong attestation is available.
But for now, a lot of apps still rely on the old SafetyNet or weak integrity. So the clock is ticking, the more up to date devices running modern Android there are, the more likely these apps are to switch over to the new system and require hardware attestation, because why wouldn’t they once everyone is “ready” for it.
I’m not sure what you’re trying to argue against, what I’m trying to say is that the technology is very dangerous and must be banned, I’m with you on user control. But I won’t fall into a false sense of security about being able to bypass everything, because we don’t have control over low level hardware as we do with software, so these megacorps have the upper hand.
