The users I know are aware of it, I made sure of that.
5 down, several million to go...
Seriously though, I think they're only doing themselves harm by mass opting-in their users.
Anecdotal Example: the deluge of 'opt-in' email that I receive has made sure I'll never opt-in to any advertisement program, and has at the same time assured that I un-check any box suggesting automated / marketing emails will be sent my way if it stays checked (such as those "Send me updates about the service" check-boxes that appear when you signup for many online services).
Now I'll be the first to admit there's no guarantee that if they didn't opt-in users that I would feel differently, but I have a feeling I wouldn't have such a grudge against companies and their automated emails if they behaved themselves. I think to some degree they are hurting their own cause.
