Stack Overflow’s content is CC-BY-SA (3.0 or 4.0) [1] and they have public data dumps [2], so they cannot make prior content exclusive.

They did at one point turn off the data dumps, early in the AI in fact and likely because they wanted to sell the data. But they were reinstated after massive backlash [3]. They could do this again and make future content exclusive. But haven’t done so yet, and if they do, it will be very public.

I bet they do. I imagine OpenAI is trying to build themselves a moat. They can't really do it with the tech, but they can try to do it legally.

Even if they don't, where are you gpnna get 10,000 H100's?

That's the great thing about AI for the big guys.. Multiple moats.
