Okay, that's an actually useful response to maybe help bridge the gap between what each of us is saying.
You see cheating as only players using the game's mechanics to gain an unfair competitive advantage over each other. I'm using it in the wider but perhaps more industry-standard way where it includes... well, basically any hostile usage that breaks the rules.
So yeah, farming and botting absolutely count from my perspective.
I do think maybe "security" is a better term to include both and "cheating" works better the way you're using it, because I do see how the average user would primarily be concerned with visible cheating that is immediately annoying and feel that "hey, people paying bot farms to buy grind eventually hurt everybody" is more of a deflection from a monetization argument than a gameplay argument, particularly in a grindy free to play thing like LoL.
But maybe you can meet me in the middle there and acknolwedge that for the devs those are both security issues they want to plug. Especially if beyond somebody selling crap to their players instead of them and costing them revenue they also add to their backend costs on top of that. And extra especially if it's wrecking some sort of in-game economy, leaderboards or infringing on legal regulations.
The Overwatch example, which you've conspicuously not mentioned, still works even with the added context, though.
