It's not a "Copilot for Emacs" though? It's a layer on top of language models APIs made for Emacs. So, if you use GPT-3, it will not be finetuned further on code like Copilot, only pretrained on data that did contain some code, and also the GPL portion only concerns that API-calling layer, not what the model was trained on, or what it can output (which is what the GPL related mess about Copilot is about).
