there's no reason for you to allow people having advantage over those who don't use it.

as for the kids who like their games colorful, shame on you.

i don't see the issue and i don't even use it lol

Making Reshade advantageous turns it into an absolute eyesore. I think the only real problematic thing for it was it's ambient occlusion plugin as it can show outlines of objects behind surfaces, but that was often the case in much older games.
