Even those important life saving items have contraindications. They are well studied. We know their benefits. We know their risks. We know how to balance the two. Professionals do it every day. Most people voluntarily choose to use these items after the facts are explained. Forgoing their use doesn't stop your life either.
We know virtually nothing about anticheat systems. Their benefits, if any, are likely exaggerated to increase profits. Their costs and risks are "explained" in some annoying legalese document that pretty much nobody reads. You're forced to accept this nonsense. You can't play the game otherwise, might as well click next.
Their function is to take over your computer in order to control and limit what you can do with it. That's an affront to the user. Accepting this costs users part of their dignity. We can only hope that they will have lots of fun with their game afterwards. Otherwise their sacrifice will have been for nothing.
