What I am inviting into the room is the ability of people to run what they wish on hardware that
belongs to them. This argument that general purpose devices used by an appreciable amount of the general public must be arbitrarily locked down and beholden entirely to the arbitrary, often greed-based whims of multinational, multi-billion-dollar tech corporations because tech-illiterate
grown-ass adults might hurt themselves on sharp edges is both paternalistic and
offensive, and I'm really quite over it.
Make the unlocking process something equivalent to rooting a modern android device (something that requires PC software, terminal commands, a number of steps on the phone, and a data wipe - i.e. something absolutely nobody will do accidentally and vanishingly few will do just because Facebook told them to) and both concerns are allayed.
This isn't some dichotomy, and treating it as such is playing right into the hands of the tech corps. This "for your own protection" thing is marketing. We already know that no principles are in play. Besides, mitigating forced obsolescence (and so, e-waste, carbon footprint, etc) is more important than Facebook getting another data point from a minority of users, and this can be addressed legislatively anyways.
