bullshit or not, that's the way it seems.
That's not the way it seems to me. It seems to me, he saw a pattern developing, and that pattern was painful for him, given his experience of what this site used to be. Rather than endure the pain, he removed himself, and set up his leaving, so that it would be difficult to return, thereby breaking the habit of coming here. He's not the only one to have done that lately.
Sometimes when you love something, it's torture to see it growing in a direction that disappoints. I think, all things considering, he handled himself very professionally. I know if I were in the same position, I wouldn't have been so adult about it. It's been my MO in the past, when leaving places, to make a big scene and then slam the door on my way out.
