Honestly, is any objective person surprised?
The whole argument of why you had to be online only for single player, to ensure single player items didn't end up on the RMAH, was destroyed when they announced you could play outside your region, but the drops you get from outside your region could not be placed on the RMAH. If they can ensure that inter-region items can't be placed on the RMAH, they could just as easily make sure offline single player items could not be placed on it as well.

Fact is, D3 smacks of Bobby Kotick-ish style of game development. I know when Vivendi bought Activision from him that he had some control of Activision Blizzard built into his contract, but still, until Vivendi wises up and fires him as CEO of Activision Blizzard he is going to destroy a lot of great game franchises. It's amazing how much of a hit Blizzard's reputation has taken since they were made a subsidiary of Activision Blizzard and under Kotick's control.
