If co-pilot is truly so transformative that copyright doesn't apply, why not feed it all of Microsoft's code to train it better? I hear this argument a lot but I think the answer is actually pretty mundane: the model behind Copilot was trained by OpenAI, not Microsoft. Microsoft has a large investment in OpenAI, but they don't own the company, and AFAICT OpenAI did all of the scraping for Copilot on their own, without any special access to MS code.
