It is as good an explanation as anything. When you are working in a rigged system you have to play by their rules. It seems odd they are not reporting on 2000 mules or at least axing questions.
It's not odd, its plain stupid and will ultimately bite them in the ass.
On the other hand their strategy is well developed since the more we rage against them the less likely they are to get sued which is obviously a key issue for them.
Once again sooner or later they will have to weigh not getting sued by ignoring the truth vs. losing their coveted #1 position in the market. Currently FNC has no real competition.
