Because the decision to leave the company is largely based upon their sudden, newfound financial security. They may give another explanation but the only thing that has actually changed is the identification of bagholders ready to cash them out.

The other issue is that the narrative about safety within these companies is largely a function of the extreme financial incentive.

As an example, Anthropic was an "ai safety" company that has now produced an AI that fails to listen to basic instructions. If you were concerned about safety, would you produce an AI that was unable to follow instructions? You ask a question, it begins executing commands and doing things.

Safety is product to sell to politicians, not consumers.

Not serious.
