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.
