What gets me is the “this phone cant be trusted” message on boot. Implying OEM roms are trustworthy, but nothing i choose or create could possibly be.
TrueNAS scale helps a lot, as it makes many popular apps just a few clicks away. Or for more power-users, stuff like the linux cockpit also really helps.
To directly answer your questions…
Perhaps more important is to have devices start or fall open… if the OEM has lost interest in it, let others support the device. Make ewaste valuable and avoidable.
