I most certainly wasn't trying to make any claims about the technical infrastructure. Sure, MAS and iTunes use the same, no question, I wasn't trying to deny that. But are there activations? That's the question. iTunes has all this UI for managing activations, the MAS has not. You can't activate computers, you can't deactivate computers. Then there's the different license. It wouldn't make any sense if you had a limited number of activations given the license. I see no reason to believe why there should be activations in the MAS. Using the same infrastructure doesn't mean anything.
