In the end we're all responsible for our own actions - but there are a lot of outside factors that influence us. The leak appears to have been a significant factor. I'm less interested in the fact that infidelity would likely have eventually lead to the divorce (though if it was privately dealt with it may not have) - I'm more curious if the timing was advantageous for MBS. This is all pure speculation, though.
I'm surprised this take is so controversial. Bezos didn't deserve to get hacked and exposed like this, but the hack exposed infidelity. The hack didn't plant fully fabricated evidence of infidelity.
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.
