Just have to see what sort of fingerprint is used to determine if the requestor is on windblows or *nix - maybe as simple as spoofing the browser to always report *nix when queried. Or more complex. I see an opportunity for a browser extension to report whatever OS you want it to report for simple cases.
I'm pretty sure that already exists.
I’m sure all sorts of workarounds will appear in order to get around, or make totally unenforceable, that law.
