come on, man, the windows Terminal repo includes code that ships with windows and is not the windows Terminal application itself. cmd.exe lives in that repo, for example, along with some of the structure which supports all command-line applications on windows.

they can't adopt GPL in that repo and Microsoft has a very strong policy about segregation between developers who can read and write GPL code and those who cannot. those who cannot interact with GPL code get to work on stuff that ships with Windows, like the stuff in the Windows Terminal repo.

so, no. they can't look at GPL code, including Casey's refterm code. Casey knew all of this when he chose the GPL for that project.
