That is the point, that EA/DICE cares more about cheaters, than they do for Consumers play legit. It becomes a downward spiral from there, because no legit gamer will ever buy your product again. Legit players are the ones who keep your base going. Cheaters move from game to game griefing people for kicks. Cheaters don't spend $2k on servers or stick with the same game for 2+ years, etc.
If you don't ban cheaters, then all you end up are with are cheaters. If you have 100 people Playing and 20 cheat, if you don't ban those 20 cheaters the other 80 gamers will leave... and that is what happened. Now, all that are left playing are cheaters.
EA/DICE doesn't care, because the legit players already bought the game. They could care less if you don't play, more money for them.
It is already been speculated, that someone at EA/DICE are developing the hacks, which are worth more than the game. That is why EA is allowing the demise of their products, because they get paid to build them, and paid to wreck them.
