You're using scare quotes, but I do specifically mean corporate control. Current TPMs were designed around giving centralized parties (eg corporations) privileged keys. TPMs could certainly be designed to not have any baked in privileged keys, instead putting the owner at the trust root. The current crop just wasn't.
Also that you're talking about anti virus shows that you're not really in touch with the gamut of computing. From my perspective, anti virus was something that was relevant two decades ago.
