Zuck apparently made a huge statue of his wife.
That seems like either the behavior of an extremely devoted husband or the behavior of a husband who cheats shamelessly and then gives her showy gifts to "make up for it"
With the blowups of 2 prominent "wifeguys" in recent years and Zuck's attempt at being more "masculine", as he called it, I'm suspecting it's the latter.
iirc, it originally was gonna be of himself but he changed it because that looked a bit too…on the nose.
I think the wife hates it.
Many of those with options see it as a badge of pride to stay loyal. One of those, ya I could if I wanted to but hey look I have self control…most of the time.
More likely he watched "Scarface" one night and got the idea that's what cool people with money do.
