I don't find a single counter-example compelling. I guess as evidence that "only moat" is somewhat hyperbolic?
But to counter the counter-example, what would have happened if he did not join? OpenAI can just write and release their own version. They can then do the typical loss-leader and advertising tricks that OpenClaw cannot.
The "simply write and release" is what used to be a barrier.
He was competition. They can't have people running their own self-hosted LLMs on their own hardware, and realizing it AI be useful without a subscription!
