I have several points to make:
1) For people like myself, PC is really the only way to play a shooter, particularly a modern one, so I would be stuck with whatever is available. I would not say my right thumb is paralyzed. . . just that an injury left it decidedly non-dexterous, and modern shooters are not kind to even the most virile right thumbs to begin with. Really, for most console shooters, I have to play on easy settings or not at all. Preferably not at all.
2) Hacking has been around in the PC space for a long time. The indifferent attitudes of developers and studios do not help, but anywhere there is competition, there will be people that are willing to throw away what dignity they may have once had for a fragment of data or a kill:death ratio. If people were to leave the PC space for consoles, the basic restrictions on hacking would come down eventually, and before you knew it the problem would be in the console space as well. The thing cheaters really desire is recognition, and they will go wherever they can acquire that.
3) Yes, Cod Ghosts is terribly unsupported by Infinity Ward and Activision; their attitude being mostly that once people have bought their product, they simply do not care. This is far more a problem with the distributors of the game than with PC itself, though.
4) You could try playing better games. Cod is effectively the lowest common denominator of video games. The video game equivalent of Katy Perry or any other base and artless pop star. So, there is that as well.
EDIT: For those saying Titanfall is going to be so much better: Please, have you already forgotten what EA did with SimCity and Battlefield 4? Those games were buggy messes.
