You're not wrong, but it's an interesting point you bring up. They were willing to stay on Twitter with Musk's antics, but it seems like they aren't willing to put up with another Musk and another set of antics.
JUST LIKE TWITTER! I love that the new internet comes in two flavors, "open source hippie (doesn't work well)" and "vaguely fascist (also doesn't work that well tbh)"
