This issue seems to have an obvious solution that I fail to see anyone mention: Treat copilot simply as a tool, let it be trained on whatever without any consent requirements. However the outputs should be subject to copyright as with any other code produced by a human. Then on a case by case basis courts can decide if infringement has occurred. The idea of banning copilot or other AI models as a whole just seems like a collective case of sour grapes because innovation and automation is finally threatening some people who only expected these things to affect the working class
