Yes, when asked he will express disdain even for projects like Ubuntu. He will say that iOS is worse, but to him, neither are acceptable. This keeps him from connecting strongly with many who are sympathetic to his cause.
I don't think people who have read a great deal of what he's said, and what others have said about him, are surprised by his recent statement about Steve Jobs. I was actually surprised that he waited 24 hours and managed to keep it short and say something to make it a little less personal (the Chicago mayor quote). I think he's maturing.
