Any form of security shouldn't be on the device anyways... It should be on the server side, other wise it's not called an anti cheat, it's called DRM software.

There are cheats which cannot be detected on server. But most of the time it is used to save server resources.

More like data miner than DRM. EasyAntiCheat and other software scans your PC for running software and sends that info back home. You have no way of knowing what else it is sending. It does prevent some cheats, but it also exists to steal your data and violate privacy. Some of them install as rootkit and might brick your OS installation, brick full drive encryption (causing you to lose your data), etc.

Also, there were cases of companies mining coins through anti-cheat software.

In my opinion any game that has DRM and/or anti-cheat is anti-consumer and should be avoided.
