The HuggingFace incident was audited by independent third party analysts. To "orchestrate" that and keep it a secret is like faking the moon landing. To many people involved. It's not feasible.
OpenAI was founded to develop safe AI. Then Anthropic split off because OpenAI was not safety focused enough. These companies have been railing about AI safety long before they had these big boy valuations. Many people at OpenAI/Anthropic explicitly joined to help make AI safe. This is not some top-down company value.
Also, I seriously doubt that "making panic" is actually good for the stock price. Usually any companies natural reflex is to cover up safety risks. That's not to say that these companies are angles. Of course they're pulling some shit but that doesn't mean that everything out of their mouths must be lie.
