Why is it always the 500 ELO complaining about “cheaters"

Like you’d have to be really bad at cheating if you used an engine consistently and still had a low ELO. Doesn’t make sense.

Someone seeing the game at a deeper level than you do doesn’t necessarily mean they’re cheating. Sometimes you just get outplayed. Sometimes people play over their rating, just like they’ll play under their rating on other days.

Is this belief based on defensive mechanisms for your ego? I understand it may be an easier cope to place the locus of control on hypothetical cheaters, but that’s not how you improve at chess.
