I don't think anyone at Apple would be all that upset over that. A publicly released exploit is better than one privately sold to intelligence agencies. It's specifically the latter market that Corellium seeks to serve.
Hence why Corellium often provides members of the security and jailbreak community with access to their services.
Corellium doesn’t charge a few “nice” researchers, but builds their business around the evil researchers willing to pay $1M/yr for a license. Clearly they’re exactly like McDonalds!
People keep making very confident but incorrect statements regarding prices offered by Corellium because they assume everyone gets quoted the same, see this twitter thread for another example https://twitter.com/therealdaneel/status/1193122030687797248
