Phones with unlockable bootloaders aren't going to be sold for much longer just like dumb TVs aren't sold anymore. There's just too much profit to be earned by corporations locking devices, plus banks and governments want to lock down phones. And once they lock down phones they'll go for desktops as well.
Maybe in the US, but not in my country. I tried looking for "signage displays" but all I could find was Samsung professional monitors that still had the smart stuff
