An idea for the fediverse and beyond: maybe we should be setting up instances with copyleft licences for all content posted to them. I actually don’t mind if you wanna use my comments to make an LLM. It could be useful. But give me (and all the other people who contributed to it) the LLM for free, like we gave it to you. And let us use it for our benefit, not just yours.

This seems like a very fair and reasonable way to deal with the issue.
