I am glad all the legal bs didn't stop MS from making the product. Copilot is surprisingly effective, it truly makes life easier for me, as a developer. The fact is that if you give your code away publicly, you cannot finely control what the world does with it. If this is not acceptable to you, keep your IP private.

If these guys manage to shut down or cripple Copilot using legal mechanisms, you can bet there will be a Chinese/Russian alternative that will be even more indifferent to your LICENSE.md, and you won't be able to get it shut down using the courts.
