TPM has to be there. If you have a machine that doesn't support a high enough version your OS vendor will refuse to give you any support and if you have secure boot disabled the software you try to run might refuse to work. Today, you can disable secure boot and have a degraded experience, tomorrow, who knows?

If this really were all only for enterprise users things like https://old.reddit.com/r/ValorantTechSupport/comments/1g4rkh... wouldn't be an issue but that isn't reality.

Then buy a machine without TPM. Or buy games that don't require TPM.

Of course online multiplayer games are gonna have more stringent device security requirements to try to deter cheaters on the PC platforms. Companies aren't gonna mass produce new HW and SW customized to your own individual desires just because you want something else than the masses of consumers don't care about.

Vote with your wallet if TPM bothers you. Otherwise I don't see what your argument stands on.
