Eh, if you're worried about politics of the form of resignations/splits/forks and their impact on technical and social decisions, I'm not sure where in free software you can go. The BSD world has had its share of strong disagreements and resignations, which is why for example Theo de Raadt is no longer a NetBSD developer, and Matthew Dillon is no longer a FreeBSD committer. Though the BSD scene is as bit more stable at the moment than it was a few years ago.
