I don't remember if it was fully proven or not, but I'm 100% convinced that at some point, Microsoft started rolling out forced updates for 7/8/8.1 systems to 10 with zero consent. No "oh well the user clicked the wrong form of later so we upgraded anyway", no they just picked a percentage of random systems they thought they could get away with upgrading without consequence and fucking did it.
Anyway I fully expect something like this to happen with 11. At least if the AI hype bubble isn't completely dead by the time 10 reaches EOL.
