Personal conspiracy theory: HIPAA data was, or possibly is, being loaded into ChatGPT without the legally required safeguards. The recent "security concerns" that caused Microsoft to cut its employees access was this information leaking out (and the leaking is possibly getting worse). Someone, possibly Ilya, found out and informed the board.
