I feel like this is reducing the problem to a simpler one. Of course you'd expert larger product decisions to be made by a technical leader. The problem here is that devices being locked down is something being fought against, repairability is a big topic for discussion, and some companies even try to play into it pretty hard, like Framework and seemingly Valve.

Yet, to this Meta CTO, this wasn't really a concern until he vibecoded something and decided everyone should be able to have this fun. It say's something about his (and probably other people in his position) awareness of public opinion and discussion.
