I want open source OSes, giving the possibility of hobbyist communities that upgrade on their own current open source android roms will disable many features because they are proprietary. even roms that include proprietary code, like lineageos, will disable many features anyway because they can't make it work while updating the android version open source should be mandatory. let the rest up to the users (if there is a strong enough community)
