It means Windows is switching to a subscription model. It could be a good thing for some Linux users, if they need Windows for specific applications and don't want to spin up a VM. O can't see a reason for using it beyond that, other than being forced to, because Microsoft kills off yoir local Windows and turns your computer for a bootloader for a cloud system, which is itself a bootloader for your browser, for most people. What a terrible world we live in. Zero privacy guaranteed, a subscription model making Windows more profitable (again).

ALSO, good luck stripping down Windows, removing bloatware, ads and telemetry. I GUARANTEE you it will be impossible to remove ads and telemetry on Windows in the Cloud. And thus that crap will be FORCED on you!
