Stream you know it's only there as long as the servers...
...but SecuRomed games, who knows how long the servers will be there, especially if it's a flop of a game.
I don't see how this is any different. Valve has said that if the Steam servers are ever shut down, they'll put out a patch unlocking all their games. Similar statements have been made on non-Steam games by other companies and I'm not aware of any SecuRom game that has been rendered useless by a server shutting down.
I'm not saying it isn't an issue, just that Steam shouldn't get a pass. And neither should Apple... because you essentially have to bypass the DRM scheme to do that and it isn't something that's going to occur to the casual user.
