Microsoft built their entire DRM software in a way that was able to be recerse engineered.

Downloading movies you haven’t paid for is also piracy even if there’s no drm. Microsoft doesn’t need to put any copy protection for it still to be piracy.

Piracy has nothing to do with copy protection.

And it’s beside the point. Using LTSC that you didn’t paid for is the same as using Windows Server that you didn’t pay for. So why not use Server which is better than LTSC?
