But of course if the data is already sitting in object storage inside your cloud environment and all you have to do is run some MapReduce jobs to get at it...

Hence: unfair, anticompetitive, intellectual-property-right-abusing behavior. Microsoft GitHub (tm) can prevent anyone else from running the kinds of analysis they do by simple "operational security", while running literally any kind of analysis, model training, etc. they want. Don't like it? But their commercial services and products so you can run Microsoft GitHub (tm) on your very own Microsoft Azure (tm) infrastructure, using Microsoft Visual Studio Code (tm) and Microsoft GitHub Codespaces (tm) so work on _your_ code privately.

Best of all, you can still still take advantage of the huge library of "free" code offered by Microsoft GitHub Copilot (tm) to ensure your private, proprietary codebase still has all of the advantages of Open Source Software, brought to you exclusively by the Microsoft GitHub Platform (tm).
