- "Linux" is bad because Android is Linux.
- "GNU/Linux" doesn't quite work because 1. ChromeOS is GNU/Linux and 2. Alpine isn't.
- "mainline Linux" is a thing we want, but still separate - I'd take Droidian with a hacked-up vendor kernel over a Pixel running an official Android image on mainline Linux any day.
The best I've been able to come up with is something like "user-controlled Linux" or "community OS" or even just "not Android", but I'd really prefer a better term.
