They don't make these games for the competitive community; they make them for general consumer. I imagine as long as the game continues to sell, they will keep doing the se thing.
While this is true, Infinity Ward has to realize how much money is in competitive gaming and how many eyes are on it. Also the fact that it is all ancillary monies laying on the table. Why wouldn't you do your best to make it somewhat similar to other games in the sense that it can be played competitively. Just my .02, I love ghosts and will continue to play it.
