The problem is that it's not just drm. The game's data and some of the simulation exists primarily in the cloud. If it were just drm they could have turned it off for a couple days to save the bad publicity.
Back on topic, I can't stand a requirement that I be online to play a single-player game. It adds no benefits to me as a player (I don't care about having achievements in an online showcase to show off to others), introduces a lot of potential problems (as have been noted above), and adds ongoing maintenance costs to the game which divert sales revenues away from actual game development.
There's something to be said for a connection requirement for DRM
