I do not use private GitHub repositories. (If I want something private, I will store it on my own computer and/or on DVDs, etc.) If they are using private data in AI dataset (or other uses) then that is a serious issue; they are copying data which is meant to be private. (Public files are public and should be made copies that others can use too, though.)
