If the fair use argument holds, there will be no possible defense against it. Microsoft will convert all open source into anonymous common property and monetize it. That's the hopeless scenario. Otherwise, the fair use argument fails to be upheld. Then Microsoft must argue that normally Copilot regurgitates a mixture of patterns from various sources, and therefore the licenses in the training data can be ignored. To defeat this fall-back argument, we must attack the root of the problem: the moment our code is used in training. That's precisely what the No-AI 3-Clause License achieves, while otherwise being the permissive BSD 2-Clause License that we know and love.
