Did u know the man personally? NO. But you're happy to denounce him, based on others comments. Do u honestly feel qualified to denounce a man you've never met? Never worked for? Who has contributed more than u ever will, to the world & to individuals quality of life? I'll point u to another quote from the book, where Steve asks a blog editor who is likewise trying to attack him: what have you ever made? I'll leave it at that, friend
Steve Jobs aside, that's a pretty weak argument. I never knew Idi Amin or Moa Tse Tung personally (I'm not comparing them to Steve Jobs), and while they made some contributions, it's no reason not to make criticisms of them.
