When I was a kid my family owned a device whose sole purpose was to rewind vhs tapes.
I own plenty of Libreboot computers without Intel Management Engine (2006-2009 era). For the average user in today’s world, I don’t see many people using them unless definitive proof came out that the government uses the IME to spy on them. These 2006-2009 era desktops/laptops can have the entire IME firmware removed, along with a 100% free BIOS. I collect as many as I can.
