The Bezos's are responsible for their actions, and their decision to divorce, but yes, the leak could have been via saudis...
I don't think "I would have gotten away with it!" is a compelling argument, but I'm not a Scooby Doo villain.
The comments about timing, malice, financial consequences, etc., are all fair for making a case that the hacks and leaks are scummy, but the Bezos's are in charge of their own relationship, or lack thereof.
