No one cares, until they spend 60 bucks on a game and find out of the blue it doesn't work one day. They do a patch one day and your game that worked fine stops playing because of some setting on your router and it takes months to resolve the issue. That's what happened to me with Half-Life 2 through Valve's Steam platform.
Look how happy the Wal-Mart drm music buyers are. If that's not an argument against DRM I don't know what is. They must have thought, "It's Wall-Mart, the authentication servers will always be there." I know they got a reprieve but how long will thst last.
