They shouldn't, because they're true!
I don't know where people are getting this notion that Sean Murray is out to Con You All out of your $60 and "Lied" about a feature that isn't actually in the game.
Until they say otherwise, YOU DON'T KNOW. So why get hung up about it? Is it because you thought Multiplayer was a significant and substantial feature of the game? The same multiplayer feature that has been cast aside time and time again by Sean as "not really the point" and hard to accomplish by players in the game? I certainly thought before launch that it wouldn't take much more than rubbing two brain cells together to figure out that they wanted direct player interaction to be a rare and special event, not something that just happens as standard in your travels. Did anyone really believe that they didn't think out the easiest logstical strategies for meeting another player in-game and then create a system to counteract that to keep meetups as a rare and special event?
Now if for some reason this system wasn't functioning properly or maybe they thought it went against the spirit of the game and decided to take it out, that is THEIR DECISION. They never made this game out to be a significant multiplayer experience. Until we know for sure, there is no reason to call him out and say he's a liar or a conman, and I think the gaming community at large is acting out of line.
