Blind fanboyism has always been there, on any side of any competition. Could be that it is just natural (which does not mean it has to be forgiven).
Yes, it's natural. It's how we organized ourselves into tribes for mutual defense in the Stone Age. Noam Chomsky calls it "irrational jingoism." It's also how countries get people to die for them in war and how sports teams market themselves.
Or google fanboys in general. Personally I find google fanboys the most annoying at the moment. Perl fanboys used to be the most annoying but there aren't many of those left thankfully.
But I do think that there is a particularly strong fanboyism attitude where Apple is concerned. People will jump down your throat at even the slightest "indiscretion", and make it a point of commenting to tell you you are an idiot.
etc.
