Besides Ver, who else are the people behind it? Andresen and Hearn?
Unlikely.
He's doing a good thing IMO, it's true that XT was arguably censored (although it's slightly academic; whether it is/isn't/would've-been-in-the-future an altcoin is a whole debate in it's own right).
I'll be checking forum.bitcoin.com out I think, although probably not joining up right now.
I think people just cry censorship when something doesn't go their way. I mean this guy's forum might not "censor" (or move) XT discussion into another section but I bet he will gladly censor in other ways. Can I call him a twat on there? Can I post his personal details or call him a scammer? Will he censor trolls and scammers or just let them troll and scam away? Creating and running a forum is never easy as it seems and many people will complain whether you do something or you don't.
