I'm not suggesting it would be an evil master plan. I could easily see Steve Jobs deciding that the Mac experience would be much simpler and better if Apple reviewed all software that went on the Mac, exactly the same way he's decided that for the iPhone and iPad.

Today OSX users are very fortunate that they don't have to deal with viruses or spyware, but the good times will change eventually and Apple will lose the marketing advantage of being able to brag about being worry-free. If they felt that their market would be interested in some kind of Apple version of Microsoft Bob then why wouldn't they pursue that?
