------
Code being copied isn't an issue. I knew full well what it meant to release something opensource and I don't regret it one bit. What was copied with no credit is the foundation of the project. How it actually works. If I were the patenting type, this would be the thing you would patent. ps. I don't regret not patenting anything. And I don't mean the general concept of package/app managers, they have been done a hundred times. If you look at similar projects across OSes, Homebrew, Chocolaty, Scoop, ninite etc; you'll see they all do it in their own way. However, WinGet works pretty much identical to the way AppGet works. Do you want to know how Microsoft WinGet works? go read the article (https://keivan.io/appget-what-chocolatey-wasnt/) I wrote 2 years ago about how AppGet works.
I'm not even upset they copied me. To me, that's a validation of how sound my idea was. What upsets me is how no credit was given.
You don't strike me as the kind of person that would litigate such things, but I would like to think that if the right people at Microsoft became aware of such a liability, they might choose to give you credit (to be on the safe side).
Apache 2.0 by the looks of things.
Interesting question would be whether WinGet is a "derivative work" of AppGet.
