I'd wager 99 % of the OSS the world runs on is people that never have cared about credit or building a portfolio.
What they do want, however, is to not have to spend time on the thousands of AI generated pull requests and bug reports.

The current point you're making is (I think) that OSS devs don't want credit, they want to be free of spam. I, for example, host my free software on fossil and don't accept contributions at all. It's not that I don't want them, it's that I don't want the noise, so I feel like that's a valid way to distribute open source.
But when I raise that, you're saying I'm moving the goalpost. I think the goalpost is in the same exact location as it has been for the entire discussion: open source authors that don't care about getting credit and want to distribute their free software can do so without any worry about AI.
If your underlying point is that AI has lowered the barrier to entry for code submissions, making previously-viable approaches to collaborative development infeasible, that's completely fair, I just wasn't treating that as fundamental to open source development in the same way you were.
