I don't see the real gripe here. Everyone's so pissy about micro-transactions being yet another way for the big bad industry to screw you. Seriously? They're giving you an opportunity to see if you even like something before committing anything to it. Boy, I sure wish other industries would screw me over like that instead of forcing me to drive a 50% devaluation off the lot...
Okay, so they're figuring out that arcades were the way to go and are now wrapping back around to it. So what? What is it now, 12 million subscriptions to WoW or some such nonsense? Apparently the idea of "ownership" as you're defining it doesn't seem to matter to them, and hell - you're probably even one of them.
You know, there was a "gaming" that used a similar model... D&D, anyone? Personally, I think DDO was brilliant when they went back to their roots and converted it so that anyone could enjoy, but just like the "modules" of yesteryear, people could still pay a small amount for additional content.
This is a good trend here, and it's not like the "owned" games will go away, just that it's high-time for a more broad adoption of this model as well.
All-in-all, I think people just like to complain.
