I don't know anyone else who got kicked out (that takes a lot). But I know of a situation where someone walked out due to a non-political disagreement. Perhaps that's the one.

I follow the community pretty closely, posters being banned (except pure spam accounts) is something I think I'd notice.

Besides, what can you do if someone walks away from an important package? Should everyone, including collaborators on that package just start from scratch? What?
