After a careful reading of the article, Facebook shot down developers/apps with Facebook in the name or using the Facebook icon.

I would assume this is in response to the horrifically bad "Facebook Ultimate" app that was top in social paid apps on iPad launch day:

I'd read the reviews to see how the 7th highest app had a single star -- all were excoriating. But people saw the icon and name and clicked Buy in droves.

Facebook did the right thing by putting a kibosh on it and any others that might come up with a search for Facebook or spotted with a Facebook "f" icon.
