From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

TPM bad, put your secrets on a proper encryption peripheral, like a smartcard running javacardOS
TPM will turn into cpu-bound DRM, the more you use it, the more this cancer will grow
You are only seeing what TPM is now. Not what TPM will become when it become an entire encrypted computing processor capable of executing any code while inspection is impossible.
Imagine denuvo running at ring level -1
Yes, it's right in the name "trusted platform module". There is no secret that their ambition is to become a space to run code outside the user's reach and scrutiny.
They start with the most legitimate and innocuous purpose. Once it is adopted and ubiquitous it will not suffer the fate of the other attempts and rotting on the vine.
Then surprise TPM 5.0 become full scale full speed trusted execution environment and it's too late to do anything about it. Eventually , non trusted processing capability will be phased out and only Intel and signed code will run.
