There were an awful lot of people, with hot blood and full pulses, that objected to things other than the sixth point. I think it was a mixture of several types of people, among these one type perhaps being those that would object to anything Steve Jobs said, and another type perhaps being those that had never experienced the misery of Flash on non-Windows platforms.
I think the parent commenter meant that disagreement with Apple on point six was widespread, rather than that disagreement with Adobe on point six was (uniquely) widespread.
