Microsoft can argue that Copilot emits a mixture of intellectual property (a pattern from here, a pattern from there), so they don't need to give attribution.

But if we disallow training, it's unambiguous.

Either you fed the program into your training system or you didn't. The No-AI 3-Clause License forbids use in training, no question about it. If you train your model on this text, you are obviously violating the license.

Systems like Microsoft Copilot are a new threat to intellectual property. The open source licenses need to change to adapt to the threat.

Otherwise Microsoft and Amazon will pillage open source software, converting all our work into anonymous common property that they can monetize.

We're watching it happen.
