As an SP gamer, I have zero interest in mmo & subscription based games of any kind, which included those that require anti-cheat measures.

My feedback is for Valve to make sure game developers don't start trying to shoe horn in tpm/secure-boot into single player games. Either because they trying to pull some shenanigans or because they are too lazy to differentiate between online or SP campaign (e.g. Borderlands).

There is NO justifiable or logical reason's for "anti-cheat" mitigations of any kind in SP games.
