Why banning wemod for a single player game, simply banning it in multiplayer game

I genuinely don’t care about achievements. Games are for fun, not for building a digital trophy collection. For me, since 2002 — from when I was 9 all the way to 33 now. Most of the games I play are pure single-player experiences.{random map and campaign} I don’t enjoy playing with random people online. The only few times I touch multiplayer is for co-op campaigns with friends. Manually copying long cheat codes, pasting them in chat, and keep jumping to the desktop is not fun, and when you play all 4 versions plus AOM together, it is a nightmare. Trainers like WeMod solve that problem perfectly — one click and everything works, no need to remember or hunt down version-specific codes. If game companies really hate third-party trainers, then make an official one yourselves. Let us toggle cheats with one click, but make sure they only affect the player — not the AI enemies or allies. Cheats like Aegis that also buff the AI completely ruin the fun. You should not use cheats in multiplayer games, but why ban them in a single-player game?
