You know, if I've noticed anything in the past couple years, it's that even if you self-host your own site, it's still going to get hoovered up and used/exploited by things like AI training bots. I think between everyone's code getting trained on, even if it's AGPLv3 or something similarly restrictive, and generally everything public on the internet getting "trained" and "transformed" to basically launder it via "AI", I can absolutely see why someone rational would want to share a whole lot less, anywhere, in an open fashion, regardless of where it's hosted.
I'd honestly rather see and think more about how to segment communities locally, and go back to the "fragmented" way things once were. It's easier to want to share with other real people than inadvertently working for free to enrich companies.
How is this worse than a human reading your blog/code, remembering the key parts of it, and creating something transformative from it?
But if we're going to dig into this a bit, one person reading my code, internalizing it, processing it themselves, tweaking it and experimenting with it, and then shipping something transformative means that I've enhanced the knowledge of some individual with my work. It's a win. They got my content for free, as I intended it to be, and their life got a tiny bit better because of it (I hope).
The opposite of that is some massively funded company taking my content, training a model off of it, and then reaping profits while the authors don't even get as much as an acknowledgement. You could theoretically argue that in the long-run, a LLM would likely help other people through my content that it trained on, but ethically this is most definitely a more-than-gray area.
The (good/bad) news is that this ship has sailed and we now need to adjust to this new mode of operation.
