If they would turn off the advertisements and let me control my feed and notifications, it might pay. I'd be mad about it, but I might pay.
FB without ads would be great, and might change Meta's incentives going forward.
On Facebook the network effect that made it cool in the beginning has now died and it will keep it from ever coming back for the same reasons it was great in the beginning. I'm very confident people I really care about will not start posting there, and they probably have the same thought process. It's just uncool.
