Hey, EA and Best Buy lay out the cash and prizes. Blame them, not the players. If you look at it, it's probably well worth it for them with all the publicity they get for sponsoring this tournament.
That said, it is a shame that someone is walking away with so much by exploiting bugs and glitches that can't be stopped 99 times out of 100. Thankfully, I think it's an all-or-nothing type tournament. If you're not the last man standing, I don't think you win anything. We can take some solace in that.
