Totally agree. Even worst, the community has already forked and is getting aligned behind https://github.com/spotbugs/spotbugs, his reappearance puts FindBugs in a very dangerous place. It either stays forked, with split efforts and APIs diverging forward, or it's shutdown to trust Bill again and hope for the best.
I for one have lost all trust on his ability to lead the project after such long absence, and the fact that he only reappeared after this hit HN, and only to respond here, to me is an indication he cares more about what people may be thinking / saying of him, than the well being of FindBugs.
I fear, the only way for FindBugs to stay alive, is for Bill to do what he probably should have done a long time ago: step down.
