I think most people should be much more questionable about groklaw. I am big open source and FSF advocate, but I'm not above thinking that groklaw is controlled/funded by a much larger power.
I hope it's just a conspiracy theory. But I do think that anonymity works both ways; it can imply that you want to say the truth unencumbered, but it also can imply astroturfing.
Just because the wind blows this way doesn't mean it always will.
