My guess is that either they’re financially super hosed. Or one group wants to build skynet and one doesn’t.
A scandal would probably be something along the lines of either “we love him and wish him the best” (hidden) or “he doesn’t represent the values of our org and we love XYz” (embraced)
It's not just a "hey, we don't really agree on x or y so let's part ways". It's more "hey, this guy did something that could get us in jail if we don't cut tie immediately".
"And lied to us about it."
I have zero knowledge of the internals of OpenAI - just thinking out loud about what could have spurred such a statement.
I don't know about the Skynet because it has happened 26 years before [1] but I imagine NSA, the Military, and other government agencies approached the company.
