Well two options if you really want to fix the problem
1) quit... maybe if everyone but the hackers left IW would get the point, not that they don't care since no one pays subs for the online portion.
2) Everyone go get and use hacks, turn them on when you find a hacker in game and "make it fair" If everyone started doing it chances are they would be more likely to take action.
yet It won't suprise me if they never do anything.... regret buying this game, and it's not even a form I can sell back (stupid STEAM)
This game will be like how mw2 is now but in a few months time and they will sit back doing nothing about It because they've earnt what money that wanted
