Didn't Google work very hard to avoid any GPL in Android, apart from the kernel? What is in there that is GPL?
I am very thankful linux is gpl. Because of GPL these tech giants are forced to release source code.
Google helped lobby the FSF to adopt GPLv3, which bans tivoization, but allows software as a service.
This is why you cannot have bash on MacOS, but Google can still use it to build surveillance capitalism, and arbitrarily enshittify your word processor.
