And honestly a great example of it working out. At least for me. I would try Lemmy off and on, and so when there was big push for people to jump off reddit I was pumped. Only Lemmy doesn't have for me is it popping up on search results, but I can just find content and talk to people all day if I wanted to.
It's probably not about the economics of remaining. Twitter's still got way more users than Bluesky.
But the optics of Bluesky are way better than the optics of Twitter, so you get to feel like you're sacrificing something (the larger user base) for your principles, while still having a huge (and engaged) audience.
They get to have their cake and eat it too. Until the crypto bros have their way with the place.
