Well there was Amazon removing some books once from Kindle accounts, and I think there were already several cases on Steam where a couple of games stopped being available as well. There is no reason why this kind of behavior would end anytime soon, and not spread further. After all, all the EULAs make it very clear the user has no rights at all when it comes to what they purchased. I'd really like stores to remove the term "buy" and replace it by "buy a license" to make it very clear that you never own anything. And on top of that, you can never resell what you buy, so it's definitely NOT ownership in any way.
