Microsoft, as a private corporation, has no business coercing a user to maintain a standard on a device that does not belong to them. Enforcing public policy through tyranny is a role that should lie exclusively with a government accountable to its citizens. The history of western democracy is littered with wars fought to ensure this is the case.
The computer isn't owned by them, but the operating system sure is. If you don't want Microsoft updating their operating system then use someone else's.
How is this an argument for Microsoft forcing updates on people's devices? Microsoft own Windows, that doesn't give them jurisdiction over people's property.
