> shatter trust with the person he purportedly loves most in the world

Well we don't know that, you are not legally required to love someone you are married to and I have no clue what their relationship is like or whether they have any sort of "arrangements". I could hardly care less really since its their private matter.

> just what might he do to you, the customer or shareholder?

I don't really see a correlation between those things. All sorts of immoral degenerates (e.g. Musk, (potentially) Gates and I assume plenty of other lesser known CEOs) have generated massive amounts of value for their shareholders.
