Generally the legitimate commercial cheat developers offer status pages detailing any of their cheats that are currently detected and offer additional tools to do things like bypass hardware ID detection if you did get banned in the past.
Maybe I'm clueless but as I understand it some of these shooters (e.g. PUBG) are games that you pay for. If one of these commercial cheats gets detected by EAC isn't the result a permaban of your paid for account? And then you have to buy the game again and make a new one, if that's possible at all? Seems like that would be a serious deterrent, although obviously it won't stop everyone. (Encountering a cheater once out of every ten matches is probably acceptable. Encountering one in every other match probably isn't.)
So yes, that's a deterrent but not for those willing to pay a price equal to the game for monthly access.
