@dsfgs what aspect are you asking about? There are many possible contexts to this question. I think I will answer just one, for now, copyright and ai.
Of course, if your using a very permissive license (MIT for example), copyright questions may not be that important to the author of that specific work. But otherwise a platform that slurps up all your code for training and then reuses it, whether whole or in part, is a copyright laundry-mat. It's not that different from money laundering.
