Reading more details in the story of an OpenAI engineer getting arrested after bugging a conference room:

Abdulrahman Alfozan, 35, a Saudi national, was arrested Friday and charged with using or attempting to use a device to intercept oral communications. He made his initial appearance in federal court Tuesday and remains in custody.

He seems to have had a fairly normal career, so what caused this flip to espionage? Strange. Not the obvious “he was a Chinese spy” that people might guess.
