I don't get that. It's very easy to activate illegally. There was also a free upgrade/activation route if you pretended to be blind or something like that. Think that's how I got a license.
It's pretty obvious that MS doesn't care if you're pirating windows. Their main market is business clients and the companies/governments they're selling your data to.
The only difficulty I ran into, is how to activate tiny10 without an internet connection.
