I'm failing to see why you are upset about this, did you expect 30 hours of content for free? Is a third the price of the main game too expensive for roughly a third the playtime? Maybe have a think about the man hours and cost involved in developing this 30 hours, 6mths, a year maybe? They can always do nothing and move onto the next fully priced game, is that a better solution?*Looks at starcraft*

Step back from what? The fact CD Red are selling DLC, when they did not before they went to consoles?
