This is a good question but I would just like to point out that 15 years ago nobody would have predicted that the questions we were asking and answering on stackoverflow would be used to train models (and that open source would have it’s license violated so brazenly) and that if you tried to delete your contributions because you didn’t want them to be used to train models you would get banned from the site, so even though adding a license to your comments might be meaningless, it might also be a powerful tool down the line. You never know how it’ll go.

SO comments are already CC-BY licensed (granted not -NC licensed, but still), but it doesn’t seem to have helped much.
