FWIW, AFAIK bitcoin.org and bitcointalk.org are owned by sirius
, while bitcoin.it is owned by MagicalTux
(Mark Karpeles, owner of mtgox).
The word "Bitcoin" has many meanings. One of them is a project to create and promote a p2p cryptocurrency. Another is an open-source project to create software for use by the Bitcoin cryptocurrency project. bitcoin.org is the official site of the latter, but not of the former. bitcointalk.org is the de-facto official forum of the former, and bitcoin.it is the de-facto official wiki of the former.
