Ironically enough, using an Intel processor with ME cleaner is more free than using an AMD processor.
(edit: HP was the manufacturer.)
Another item of interest may be printer stenography, in which every piece of printed paper, seemingly from every printer, can be traced back to make, model and potentially even the unit used to print it: https://en.wikipedia.org/wiki/Printer_steganography
(Meaning that I always assumed something like this was going on, because that's what I would do, but I try to disbelieve it so as to be able to act normal. I believe all phones are continually listening to and scanning their ambient environments, because that's what I would do. But probably not, right? Right?)
The thing that bothers me the most is that "normal" people refuse to engage with reality. I used to tell people some of the things e.g. that Snowden revealed, but I was always accused of wearing the tinfoil hat. From my point of view, normal people are hugely intellectually dishonest. Poor Ed Snowden had to throw his life away to try to get people to notice and think about what's happening, and typically all most people do is whine about their precious privacy (the ones that don't immediately stick their heads back into the sand that is.) Like privacy is something that still exists. It doesn't.
I better wrap it up here before I get the urge to talk about forbidden technologies like REDACTED, REDACTED, and REDACTED. I mean, there's a certain tension knowing about a REDACTED that can cure all diseases, but that cannot be popularized because it can also REDACTED without a trace. Could you imagine the chaos if something like that became public knowledge!?
I still don't use facebook and I run free/open-source software exclusively, but worrying about it didn't change anything.

"AMD seems not to use the brand name "AMD PSP" anymore. Instead some years ago they began to use the name "AMD Secure Processor". Nevertheless it is just the same: Read the small footnote at http://www.amd.com/en-gb/innovations/software-technologies/s... which begins with 'AMD Secure Processor (formerly “Platform Security Processor” or “PSP”)'."
