Aah, the pitfalls of an open system.
On what planet is Android open? I can't even load my own version of it on "my" own phone unless I make sure I spend more to get one of the very few models that offer an unlocked bootloader any more. Even then there's 100MB+ of closed crappy firmware, drivers, etc. that can't be replaced.
The pitfalls of a TiVoized, centrally controlled system perhaps....worst of both worlds since Google gets to claim they don't have responsibility (guess what, locked loaders mean you DO have responsibility on e.g. the Pixel, let's dish out some GDPR fines until you get that through your thick corporate skulls....)
