According to domaintools, bitcointalk.com has been created on December 31, 2010 while bitcointalk.org has been created on June 23, 2011.
So I don't think bitcointalk.com has been created for phishing purpose. That's older than the real bitcointalk.
By the way, was bitcointalk using another domain before June 23, 2011?
Satoshi created his account on November 19, 2009.
Edit: I just found the following post from theymos.
It's probably already settled that forum.bitcoin.org will move to bitcointalk.org, but I'll post my argument against the move anyway. Bitcoin.org has no claim to being "official" other than it being the only Bitcoin domain that Satoshi ever owned. The client doesn't link to bitcoin.org anywhere, and no resources are actually stored at bitcoin.org. It's not even the first Bitcoin forum: the sourceforge.net forum used to be used by Satoshi. Therefore, I see no reason why the developers should take bitcoin.org from the community that has been located here for over a year. The main bitcoin.org page can be treated like a "fan site", or it can have its forum links removed, or it can disappear entirely for all I care.
I didn't know this.
