The funny thing is that, like many have said, most developers are horrible for this kind of BS, that's what lawyers are for. that said, I can't recall Sony ever doing this. (not saying they never have, but I've never seen it or heard of it). In fact, I've seen plenty of people saying that Sony is known for being very 'hands off' when it comes to developers. It gives more freedom,so it's great for developers like Media Molecule or Quantic Dream to make something unlike anything you've seen before.
Sometimes they really pump marketing into a game, but there's no denying that it also has the potential to lead to a lot of detachment from developers.
But I think the main reason XBLA is better than PSN is that vital American market. Americans tend to have more disposable income than other nations, so more people are paying for XBL, and therefore are paying for more XBLA titles. Just a theory, of course.
