So… what is happening here? All these people are opting out of having their content recorded as part of a corpus of open source code. And I'll probably do the same, because "The Stack" is falsely implying people have permission to use it for ML training. But this means "The Stack" has put a knife in the heart of publicly archiving open source code at all. Future attempts to preserve OSS code will, if they base themselves on "the stack", not have any of those opted-out repositories to draw from.
