Canonrumors has shut down the forum

no explanation given. They're not even selling it. Legal issues?..

Money and the cost of administrating a Forum.

Nobody cares anymore about what the latest upcoming little tweak to a companies cameras.

Hmm.. If the cost were the main reason, the owner would've probably have attempted to sell the forum before shutting it down.

Cost is certainly a factor. For example 'DPRevived' which was started independently when DPR was shutting down, or had done so, has said recently that they would have to shut down soon without further funds. There, sponsorship is still voluntary and members have indeed responded, some quite well!

There's now the second article that says the money was the main reason www.canonrumors.com/more-information-about-the-closure-of-the-forum/
Still a bit puzzling why he didn't want to even attempt to sell it: "We have no interest in selling either the forum or the Facebook page." Facebook page will probably be worthless, but the forum is a bit different thing. Maybe the legal costs associated with the prospective sale are higher than the cost of the forum.

Anyway, in the end there's now one photography forum less.
