This is called a bad game, which FF7 has always been. Now they have added the ability to turn off the worst part and finally see all the positive aspects for yourself. This is not cheating, this is common sense.
People are whining mainly because the speed at release was broken regardless of whether the acceleration option was turned off or on, a patch has already been released for this.
Plus there is a fairly large sect of mentally ill people who need the old mods to work on the new version, they also add negativity to the game, instead of waiting a little.
