I don't mean to be rude, but when has that writing not been on the wall? You can find scripts to activate Windows on fucking github. Like maybe people would be less apt to steal it if it wasn't so insanely simple to do that you could automate the process in a bat file?!
Add to it, I'd bet money the VAST majority of the time, people are using those things to install Windows to devices that already had Windows installed legally from the factory, with a legal license purchased by the OEM, that Microsoft refuses to, and has refused to permit users to reinstall with since I was a young bab in 1999, despite the fact that my GRANDMOTHER knows that the longer you run an install of Windows, the worse it performs, because it's poorly engineered.
Personally, I'd be fine paying for Windows if I could buy perpetual, permanent licenses for it that I could install with repeatedly, and that the OS wasn't constantly shoving ads in my face, haranguing me about using a stupid Microsoft account, and using enough telemetry to enable identity theft. But Windows licensing has always, always been exclusively the domain of PC manufacturers and corporations. Microsoft refuses to make it even slightly better to use for users, which is why users by and large just crack it and get on with their lives. $200 for a key you can use three times is fucking absurd.
