Exits are not enough. We must push for at least as many social media servers as we have web/email servers today. If you put out content or have a public presence, you should want it to be social to ensure that no person, corporation or govt can limit your reach. That everyone who will be interacting with your work is also similarly free to share it, w/o competing with ads/algos. That's the promise of #ActivityPub and where the #ATproto model falls short.
