Hello. Many of the older thinkpads were regarded as being peak for the ability to repair and easily see into them at both the hardware and software levels.
I was wondering, what PC, if any, is similar in this regard? Aside from building your own PC ofc. Any opinions are welcome. Thank you.
They absolutely do not record keystrokes and phone that home. You’re talking about the Intel Management Engine, which is completely useless to almost everyone, but there’s no evidence that it spies on you. There have been security vulnerabilities found in it that could let someone else compromise your system (notably: only if you’ve provisioned Intel Standard Manageability), but there is practically zero chance that Intel is doing that or even selling that sort of capability.
Pretty sure this section of the Libreboot website talks about what you mentioned if OP wants more info
