It's not a separate problem, Google are actively suppressing any possibility of open mobile hardware. They force HW manufacturers to keep their specs secret and make them choose between their ecosystem and any other, not both. There's a humongous conflict of interests and they're abusing their dominating position.

> They force HW manufacturers to keep their specs secret

Spoken like someone who has never ever worked with any hardware manufacturers. They do not need reasons for that. They all believe their mundane shit is the most secret-worthy shit ever. They have always done this. This predates google, and will outlive it.

Often it is because they don't know their own devices. We got a dev board from Qualcomm once and the documentation was totally bogus.

Regulating this is the way to not let general computing die to fuel google and apple profits.

People should have the right to run whatever software they like on the computing hardware they own. They should have the right to repair it.

The alternative is that everything ends up like smart-tvs where the options are "buy spyware ridden crap" or "don't have a tv"

Given how antitrust is not really working right now I would say this is debatable. Also monopolies in the past were forced to do various things to keep their status for longer.
