In an article titled "The Not-Quite-Ultimate Fighting Championship", Slate.com tackles the issue of Fedor not signing with the UFC very well.

At a certain point in the development of any sport, a single league or promotional body becomes synonymous with the sport itself. Ultimate Fighting Championship, which recently partnered with ESPN and is promoting fights that are about as successful as the biggest Mike Tyson bouts of yore, has basically reached that point. All of which makes it awkward, at the least, that the best fighter in the world doesn't work for them. UFC may be to mixed martial arts what MLB is to baseball—but Albert Pujols doesn't play in Japan.

Slate.com has covered MMA in the past, sometimes favorably, sometimes not.  It's overall a very popular website (liberal leaning).  The fact that they bothered to do the research and get their facts right without siding with either Fedor or the UFC is the unbiased coverage the sport needs to grow in the public consciousness.  No one is the villain in it, with the writer criticizing both camps.  They explain the issues clearly, relating it to the lay reader is ways like "UFC fighters are paid like door-to-door salesmen. Heavyweight champion Brock Lesnar and welterweight champion Georges St-Pierre each made nominal base salaries of $400,000 for their recent title defenses. They picked up the rest of their pay on commission."  It's a great read, if nothing else to see a site that has defended MMA from the beginning.
