I am one of the people that got the Crimson DLC for free. It pretty much threw itsself at me when I turned on the game the other day ( I.E. Halo 4 start screen appears, prompted to download the Crimson DLC). I wasn't gonna say no, but I hadn't considered the folks that paid for it. Today, I turn on my Xbox and DL the latest Halo 4 update, enter war games and no Crimson DLC. I'm just curious what the "Official" word is on this. Was it a mistake, a glitch, was it on purpose, what? I agree that it isn't fair to those that paid for the content, but it seems kinda crappy to just take it away from those that got it.
Additional thought:
Perhaps its like the proverbial crack dealer. Give it away for free until the person is hooked, then you're almost guaranteed a paying customer. I would prefer to believe that 343i has better ethics than that though.
Still a fun game even without the free DLC, may or may not buy the extra maps, haven't decided.
