I guess AI companies are actually super happy with major open source projects having such policies. It guarantees that their source code repositories will remain amazing assets for the training dataset construction. Open source projects don't buy massive licenses anyway - the paying customer is in the enterprise not in open source. So it's fine for open source to go without AI and by doing this contributing to AI models becoming better and better.

So all in all, a good news to everyone :) Both the "pro-AI" and "anti-AI" crowds.
