Yes, I am aware that the Fediverse has a superior product in many ways, and is likely to outlive Bluesky, as well as other platforms. I do nudge people over here from BS when I can.
But the problem with Mastodon isn't the tech. It's the purist condescension, the constant sense of bitterness and sour grapes. This is a social network, supposedly. Ditch the antisocial behavior if you want people to feel welcome.
