I doubt that works. They would be fine keeping it up indefinitely as their internal Slack. What I think would work better is to just keep using it like nothing happened except a child with skill issue has been ruining it, which require no pretentious, deliberate, or dishonest behavior. The Twitter HQ had always fought its userbase and culture, not always relentlessly with passion, but never really loved it. The relationship between Twitter, Inc. and its user hivemind was always Clockwork Orange toxic. Though Musk trying to ruin it and getting his brain absolutely deep fried in a massive brain inflammation is his own doing, Musk ending up owning it in the first place, for the large part, is result of its former owners throwing in the towel.
