You’re missing the point: Copilot depends on being exempt from copyright restrictions, so that the license, any license, is irrelevant. Simplified, copyright law says “the creator/rights-holder owns the thing and you can’t do anything with it unless they let you (grant you license), or one of these general conditions holds”, and Copilot is not using your code under rights-holder permission, but under the general condition of “fair use”. If the fair use doctrine fails and the license is relevant, there’s still nothing special about GPL, because almost all licenses would be being violated in some way (most commonly starting with attribution requirements). In this situation, Copilot will certainly be discontinued immediately.
