Realistically I'm not leaving GitHub anytime soon and I do agree that businesses need a way of making money. I'm generally fine with a free service that also restricts certain features to paying customers and I think that GitHub worked well with that formula so far. But I don't like the double standard highlighted in this article about Copilot: they are training their IA on Open Source repos and using the result without taking into account possible licenses incompatibilities by making an argument about this being comparable to a compiler's output, but at the same time they are not using their proprietary codebase to train it to protect their own intellectual property. I'm not saying that businesses have to provide stuff for free, I'm just saying that there are if not more legal at least more ethical ways of making money, because as it stands now it seems to me that Copilot is in a legal gray area.
