This, Samsung, BP, et al. have to pay someone to troll their competitors... Apple gets chumps to do it for free.
What makes you so sure about this?
I have yet to meet a real life apple fan (and yes, i know some people who have pretty much all available kit) that behaves anywhere near as stupid as the common internet troll. Sure, anonymity might have something to do about it, but i really doubt there are that many people who actually care about Apple like a religion.
