@sun@mangeurdenuage Computrace https://www.youtube.com/watch?v=er9sAereb30 Mastercard put out a freeze on a bunch of machines (some of which they probably shouldn't have.) I don't know if there's a newer version of it that's more invasive, but I know in the past I've called the Computrace people and had locks removed from Thinkpads before I installed coreboot. They're not stupid, they know machines get decommissioned and get (legally) sold second-hand, so I don't know why this guy got told to get stuffed.
@sun@mangeurdenuage I was wondering if it was some magic Microsoft-developed MDM software that he got caught in the crossfire of, which is why I went and looked for the source. Nope, just Computrace.
