But by OpenAI's telling they heard a rumor that the problem had already been solved. So they reached out to the other researchers as an attempt to share the credit, and in fact have at least one of them be the lead author (which is when they found out the AI had solved a broader problem than the researchers.) Seems pretty ethically palatable.

I suspect the main reason the community is not receiving it well is largely the same reason many developers are not receiving coding agents well.
