Plenty of people will gladly give you their hard work for free if you promise you'll return the favor. Or if you promise not to take your work and make others pay for it when they could just get it for free. Basically, help the people that want to embrace the freedoms of open source, but not the ones that are just in it for the free labour. Or at the very, very least, include a little "thank you" note.
AI doesn't hold up its end of the bargain, so if you're in that mindset you now have to decide between going full hands-off like you or not doing any open source work at all.
Given the amount of value I get from having AI models help me write code I would say that AI is paying me back for my (not insignificant) open source contributions a thousand times over.
Good for you, I guess? That doesn't really change the situation much for the people who do care and/or don't use AI.
I consider the payment I and my employer make to these AI companies to be what the LLM is paying me back for. Even the free ones get paid for my usage somehow. This stuff isn't charity.
