GitHub Turned into an Enterprise Under Microsoft?

I was requested to remove a training file from my Deep Learning Language detection repo (only 64 stars but still). The repo used Deep Learning to detect programming language of a file or snippet. The files and snippets were harvested from public files and snippets of github and stackoverflow. The repo was taken down even after I removed the file from the git history.
