I'm not sure I follow a lot of your points about moving from an open OS to a closed one, Mac OS X is still very open (http://developer.apple.com/opensource http://developer.apple.com/opensource). They blatantly said they were adding iOS-inspired touches to Lion and I don't think this will have any consequences for the open source base of OS X. I don't have any knowledge about the removal of Samba, but I wouldn't get too worried. As for Bertrand Serlet, his departure was planned at least a year in advance. I doubt it was anything to do with open source or iOS taking over.
