"people hated the first Windows 10 builds so much" I don't remember this at all, quite the opposite, I remember being one of the last to switch from 7 to 10 at my company, everybody on 10 was quite happy.

I don't remember any popular software releases called ShutUp7 or ShutUp8, just ShutUp10.

As a software developer myself, I consider it a bad sign when other people make money selling software to change the way my software works.

Windows 10 was published almost 8 years ago, it changed quite a lot since then. Look at shutup10 changelog, first versions features were quite different.
