I think your thinking to much about this.
So far the poll shows 100% support for it, so I'm not totally alone.
EDIT: It did at the time of writing at least.
I was just thinking about how best to tell someone about a game like Journey. Sure, it's a coop game, but if I tell them it's a coop game and say they can't play with their friends, they'll think it's a sucky game, when it's really a great game (I'm in the beta, it's awesome)!
