Let me tell my management they no longer have to pay windows license for the ~10,000 user machines, and then the servers.

While a single consumer can get away with it (and MS doesn’t care because it means they’re using Windows and likely using MS services, all while getting telemetry from the desktops), it’s far from “nobody buys a windows license any more”.

Even SMB’s will pay, because if they don’t MS will hammer them financially. No SMB could stand up to what MS can do to them - $200 windows license is cheap insurance.
