@SuperDicq @nyx > Linux phone, while Android just is

Yeah, the one thing that Android isn't is Unix, that's the model that Android explicitly throws away. (See how anyone wanting a Unix environment on Android installs termux, which could be compared with Cygwin or WSL, specially in how it ends up jailed in a corner)

Could also put that SailfishOS (among others) isn't a gigantic monolithic system, but instead atomic system packages, so you can throw away stuff you don't like as well as replacing bits like a ship of thesus, something you can't cleanly do with Android.
