Nice to see people jump on the Blizzard hate wagon. I guess some people never get with the times.
Let me point something out here, I never even noticed StarCraft 2 was always online, except for one case where it wasn't since Blizzard was doing maintenance/patching that was told of a while ahead, so my bad for not noticing. Also, saving to my online account was a real life saver, since I upgraded my computer, and everything was deleted. I had to reinstall StarCraft 2, along with a bunch of other non-online games. My non-online games? All data gone. StarCraft 2? Only my replays which are saved to my hard drive were gone, everything else (achievements, single player progression) were A-OK. I had a similar situation with Steam, and saving to the Steam Cloud.
Not to mention, if they look at your gameplay, its not to get off to. With StarCraft 2, they look at replays to better balance the game. I'm sure they'll do the same with Diablo 3. Stop being paranoid saying "I don't want them looking at my games!" It's not like you do drug deals in there (at least, I hope not). They are just trying to give the best, most balanced experience they can, and sometimes feedback in the form of forum posts just doesn't cut it
