The conspiratorial answers here are emotionally satisfying, but ultimately wrong. The reason chip makers and OS vendors are adding this is customer demand, by which I mean enterprises. Companies want remote attestation and guaranteed-immutable OS images on their networks, and I honestly can't say I blame them. In a perfect world they could have it and we could somehow firewall it away from the consumer space entirely, but that's not going to happen.
