Wonder if Google, Apple, or SoC makera are asked or secretly mandated to leave certain backdoors in. I know mobile providers have quite a bit they can see on their end.
It's a good thing we're always presented with two choices for everything, like mobile OS's, to control our choices like we're toddlers.
Not everyone has strength of conviction he does. Companies look for the weak link, how can they buy off or stroke the ego of.
Adding some T&C's in as OP suggested could be a good idea. Sure they can ignore it, but it'd be good to put in as many road blocks as possible to prevent the enshitification attacks that will eventually come in the distant future.
