We need to fight Google's new ID requirement for app developers. It isn't like showing ID at the airport. More like showing it at the printing press and only IDed authors are allowed to print books.
What Google doesn't talk about is that they build this ID system to ban developers and their apps.
Unfortunately, developers on Google Play are already used to this system and people have accepted Apple, so I this will be a hard fight. Digital ecosystems being closed "to keep us safe" isn't seen as a bad thing.
People saying "But I use a degoogled custom ROM, so I won't be affected" are missing the point. Apps not on Google Play are already a niche. Banning them on most people's devices is a big issue, even if some people can still escape.
Also the general trend of Google becoming more closed may make even custom ROMs impossible eventually.
