I think one point of defence for this would be that it's so obvious that Fox is biased, that it need not be mentioned.
I think Joe also mentioned at some point that he used to read and watch CNN a lot (and he implied that he trusted it at the time), so perhaps this is the reason why he's now putting it down.
