Edit: I'm wrong about this one. It's an actual article, and a pretty good one at that. But it is either a mistake or they are introducing an alternate expansion for TPM (other acronyms have been given different sets of words).
"Trusted Platform Module" sounds good. But what it actually means is that the platform can be "trusted" to place the interests of third parties over the owner of the device. Stallman referred to it as a "Treacherous Platform Module" because he saw it as betraying the user.
I'm guessing that "Technical Protection Module" is a similar attempt to "de-propagandize" the acronym, and that it caught on with some group of users long ago.
People make mistakes sometimes. And this one is not a huge one -- the meaning is conveyed fine.
As we all know, ChatGPT stands for “Chat General Purpose Tool”, as it is an artificial general intelligence.
