That's not the same; not enforcing "realism" (for want of a better word) isn't the same as cheating. A more appropriate example would be something like "when was the last time you played a shooter where your crosshair didn't stick to or gravitate towards enemy targets?".
That's rather common, too, among less-than-absolutely-hardcore-fps games which are still shooters and played in first person or over-the-shoulder. There's quite a few games in the genre that give enemies more health and weaponry than you have, but grant you superior tactical options.
