If you're so annoyed with it, just don't buy it - simple.
If there's something about it that makes it worth pirating to yuu then don't bother crying about them not supporting dedi, because whatever they did put in the game was important enough to you to warrant pirating it.
Important enough to pirate, yes, but not enough to justify the price tag. Not that I intend to pirate this game, and I'm not supporting piracy in any case, but people seem to look at the issue as far more back and white than it is. There are shades of grey between not wanting to play the game at all and wanting it so bad you'll fork out full price for it.
