I think that we are seeing the symptoms of a team (Twitter) who is not yet used to Musk's management style, whereby he says something like, "we should do X", and he means, "we should investigate and take reasonable actions which have the same effect as (the too-bold action) X". The team interprets the first statement too literally and actually does X, which isn't really what Musk intended. I developed this theory in the roll-out of Twitter Blue, because it matches what happened very closely: Musk publicly said "hey we're going to start charging for verification and it's no longer a mark of validated identity". The team jumped and made something overnight, but this was rolled back because it's not what Musk meant for them to do. Rather, what he meant for them to do was sit down, plan what to do, and then execute it - quickly, but not immediately. And that's what happened in the end, i.e. in the past few days.
This effect is exacerbated by the remaining employees at Twitter including those who are most eager to suck up to the new boss, frankly, leading to them jumping and doing what he said (over-literally).
Anyways, the same theory would explain the elonjet thing. Elon says, "hey posting people's real-time location is generally seen as a bad thing, like that elonjet guy, we should look into a policy against that." Overeager underling takes this as a commandment to ban elonjet. More reasonable people who are beginning to catch on to the management style go and actually develop the policy; once it's developed, it makes sense to just Ctrl-Z the actions of the overeager group.
