If the goal of beehaw is that the user base remain ever small, then by all means jump ship and move on, I can respect that and I wish you all the best. However unless your good faith "rockstars" are planning on building you a platform, you will likely find out that the grass is not always greener on the other side, and that migrations bring additional tensions and work.
Rather than cultivate a friendly and open community, they decided to be hostile and closed. I am not surprised by this at all, but I am surprised with how long the decline has taken. I have a number of bad/silly experiences on stackoverflow that have never been replicated on any other platform.
