I agree with this article, but I think it can be summed up as, "People need the option to buy the LTSB release of Windows 10". Microsoft refuses to sell it to consumers. It is an enterprise only option (unless that has recently changed and I am not aware of it).

I have one windows 7 machine for playing WoW and it will stay on 7 until I can get the LTSB release of Windows 10 and the ability to turn off 100% of the telemetry, for real. If Blizzard would build an unsupported 64 bit ELF binary for WoW, then I would not even have windows. I'm not using wine.

Then pirate it. What do you care? This is like pirating a show they refuse to put on Netflix. They don't give you the option to conveniently buy what you want, so pirate it.

Pirate KMS servers will go offline eventually right? Even if the legality isn’t a concern, the reliability and maintenance overhead is a problem. There are trust/malware concerns with client-side cracks as well.

If you want to skip straight to the piracy, here's an open source package for you, complete with keys, hosted ironically on Microsoft servers, that uses vlmcsd: https://github.com/ekistece/vlmcsd-autokms

It's a pretty clever hack. It runs the KMS emulator locally and fakes the network connection with a TAP device from OpenVPN. Works perfectly.
