We should have the ability to run any code we want on hardware we own

This makes the point that the real battle we should be fighting is not for control of Android/iOS, but the ability to run other operating systems on phones. That would be great, but as the author acknowledges, building those alternatives is basically impossible. Even assuming that building a solid alternative is feasible, though, I don't think their point stands. Generally I'm not keen on legislatively forcing a developer to alter their software, but let's be real: Google and Apple have more power than most nations. I'm all for mandating that they change their code to be less user-hostile, for the same reason I prefer democracy to autocracy. Any party with power enough to impact millions of lives needs to be accountable to those it affects. I don't see the point of distinguishing between government and private corporation when that corporation is on the same scale of power and influence.

For smart people it is not impossible. Just few years ago, few folks wrote complicated drivers for completely closed hardware, and I'm talking about M1 Macbook.

Google Pixel, on the other hand, was pretty open until very recently. I might be wrong about specifics, but I'm pretty sure that most of software was open, so you could just look at the kernel sources in the readable C to look for anything. You can literally build this kernel and run linux userspace and go from there to any lengths of development. Or you can build alternative systems, looking at driver sources.

I don't understand why mobile systems do not attract OS builders.
