FR. I deleted like six years ago, but it’s too bad FB, Meta is like this. Lots of people have massive sunk costs. I was tangentially part of an online education company that trained people in digital arts that used some FB service for its class discussions, and it was a really high quality experience. When FB decided to up the cost, the school bailed to discord, but discord is terrible for that kind of thing.
Nostr can replace them over the long term.
