One of [[Windows 11]]'s operating system requirements is TPM 2.0 implementation.

In 2015 [[Richard Stallman]] suggested to replace the term "Trusted computing" with the term "Treacherous computing" due to the danger that the computer can be made to systematically disobey its owner if the cryptographical keys are kept secret from them. He also considers that TPMs available for PCs in 2015 are not currently{{clarify timeframe|date=December 2022}} dangerous and that there is no reason '''not''' to include one in a computer or support it in software due to failed attempts from the industry to use that technology for [[Digital rights management|DRM]], but that the TPM2 released in 2022 is precisely the "[[Trusted Computing|treacherous computing]]" threat he had warned of.<ref>{{Cite web|title=Can You Trust Your Computer? - GNU Project - Free Software Foundation|url=https://www.gnu.org/philosophy/can-you-trust.en.html|access-date=2023-09-06|website=www.gnu.org}}</ref>
