It seems to me that it's inevitable that if we let these megacorps control our devices, they will use it against us in one way or another. The only way for us as users to actually have freedom, security, and privacy is if we can control what entities the device trusts ourselves. We must create choice where the corps would rather we have none.
I will also point out that I consider Apple's rent seeking and censorship, that is more or less literally impossible to avoid, to be unethical use of this power they wield over users, and a pretty clear and meaningful way that users are harmed by it. In very concrete ways it can be considered more harmful than malware. But few seem to care enough to ask for control of their devices back, and in many of these threads more seem willing to jump to the defence of these practices than see them as a problem.
