Good idea, not-so-great execution. I think this would have been better if the author wrote in a more serious tone.
I think the point is that if you want to, you can probably conjure a logical-sounding, professional explanation for just about any 'evil' action by a company. From their standpoint, when isn't it logical to do something that hurts the competition?
I'm not saying the explanation John Gruber came up with (and was later reaffirmed by Steve Jobs) is false. I just don't think it makes Apple's actions much easier to stomach.
