Anything released from this point on is suspect for llm generation assistance. Part of sharing is to show proof of being able to do this work to others. I feel like that no longer is true so I would rather leave things untouched with older dates for fear of tainting them.
Do I want others to generate my project claim credit kick me out of the loop? Not a big concern but not really.
Code was gold now it's an output of a vibe and seen as worthless.
It's up to you. Stallman argued that the greatest value code has is it's utility to others. The "holy grail endgame" of open source is zero-margin software production that completely displaces the need to generate value with software. If AI pushes us closer to that world, then I can sleep well feeding it code.
Only from a point of understanding this context does your question make sense. Without this context all answers are equally valid and equally useful. And since few replies will include their context it will be hard for you to discern which match yours.
Personally, no, I don't care about training LLMs. But it's unlikely that my context matches your context.
In case of artists, them being able to make a living was an aberration to the historical pattern, specifically predicated on creation being hard and reproduction being easy. Before 20th century or so it used to be hard/hard, now with GenAI we're at easy/easy and neither can sustain them. Add to that their idealism and that is where it comes from. The "you can become anyone you want" and "follow your dreams" we all were told did not help either.
And if it’s open source under Apache/MIT license I could care less about people getting snippets from my code.
In fact, if there was a better, more direct way than publishing on GitHub to feed my open source code directly into future training runs, I would probably do that.
But then it fails and I make it open source to add to my portfolio.
