The “OS companies” are already there. Windows, macOS, and iOS all send vast amounts of telemetry to the cloud.
Apple is aware of all hackintosh installs out there. Microsoft is aware of all un-activated Windows installs.
Clearly now, unlike the old days, they’re not too concerned about it. I remember a couple of times where Apple quietly issued a macOS fix that fixed a hackintosh-specific issue.
Pirated installs get additional users onto their service platforms. Their cloud service platforms are what OS vendors care about.
