Whether or not DLC is worth paying for depends on what is added. CoD4's certainly wasn't worth it, because a single map isn't worth 2.50, and it being free on PC makes the price seem like a total insult. Something like The Lost and the Damned, however, is worth paying for. I may not like it at that price, but then again I don't even have GTA4 or a 360, so I won't pay it regardless.
Of course, what the guy is really complaining about is MS policy and possibly Sony policy (though it could have been charged on PSN because of the charge on Live, where it was released 3 weeks earlier). They are the ones that feel the need to nickle and dime the customer. If they were willing to give DLC away for free for PC they would have done that with 360 and PS3 too, if they could have.
You do not have the right to never be offended.
