Whatever the parent company, Blizzard's earned some trust, at least in my books. Until the day they do screw over a fanbase by taking down an authentication server and providing no patch, I'm not about to get all high horsey on them just because they require me to prove that I actually bought their game.

As far as DRM goes, this is so slight that I really can't see the problem. It's not like this is the first step of the slippery slope, either. Plenty of other companies have already done much worse. As far as I'm concerned, Blizzard's stance here is an entirely reasonable middle ground between customer convenience and support versus the need to deter piracy. Watching people scream even about this is discouraging, because what do you expect companies to do?

If you think that the majority of people who pirate videogames are so noble that they will immediately lay down their arms and start paying for all their games if there is no copy protection (meaning that all the games are suddenly available for free even more readily than they are today), then I don't even know what to say. That'd be a great world to live in.

Do you know that at least 25 percent of people pirated the indie game pack that was up a little while ago? The one where you could name your own price, as low as $1, and you could designate that the money go to charity if you wished? Yeah, online pirates sure are noble.

Companies aren't going to stop trying to protect their games. You have every right not to purchase those games if that really offends you, but in this case I just can't muster any righteous indignation over the possibility of one day being screwed by a company that doesn't exactly have a track record of screwing people.
