You mean like their recent Wine patches, which they trough over the fence instand of working with the community? WebKit was forked AFAIK for open source projects etc. Perhaps Apple conforms to the letter of the law, but they for sure don’t play nice to the spirit of OpenSource. Finally: Given what they borrowed from the *BSDs, I don’t see Apple being a contributor to the *BSDs in any way.
