Almost none of the original work I've ever posted online has been "given away for free", because it was protected by copyright law that AI companies are brazenly ignoring, except where they make huge deals with megacorporations (eg openai and disney) because they do in fact know what they're doing is not fair use. That's true whether or not I posted it in a context where I expected compensation.
I just don't think the AI is doing anything differently than a human does. It "learns" and then "generates". As long as the "generates" part is actually connecting dots on its own and not just copy & pasting protected material then I don't see why we should consider it any different from when a human does it.
And really, almost nothing is original anyway. You think you wrote an original song? You didn't. You just added a thin layer over top of years of other people's layers. Music has converged over time to all sound very similar (same instruments, same rhythms, same notes, same scales, same chords, same progressions, same vocal techniques, and so on). If you had never heard music before and tried to write a truly original song, you can bet that it would not sound anything like any of the music we listen to today.
Coding, art, writing...really any creative endeavor, for the most part works the same way.
That Trump is even near the reigns of power is obviously an indictment of many facets of American culture and politics, but it doesn't really wash out to every individual American bearing responsibility the way you're suggesting here.
We're all stuck with some shared ownership for what our country does even if we detest it.
