How you come to this assumption is beyond me.
First of all no-one is accusing anybody of anything. We can simply detect when a controller or mouse is more forgiving than the norm. The person using that device will get a message informing them of that so If they want to play the game as intended they can disable either axis adjustments or angle snapping in their controller software if it's installed. If their controller has none of these features they can carry on playing in the knowledge that the game is playing easier from them than it was designed to play.
PS 'cheating' discussions which is entirely different thing are not allowed in our forums so bear that in mind when posting.
I do not believe that the discussion is about cheating but rather about the use of equipment available on the market which is deemed to give a person an unfair advantage or 'not playing the game'.
My own personal feelings are that if some one wants join a tournament then he or she will have to conform to the rules and regulations of that tour but off the shelf, non modified controllers are there for anyone to buy and to use and the person and/or the controller should not be demonised by others.
I use the Speedlink because it is more comfortable to use and has a matte finish which stops my hands from sweating, nothing more.
