f you're wildly successful at something with significant real world influence, why would you care so strongly about something as relatively inconsequential as a board game or a video game?

Zuck 'earning' another billion probably means nothing to him. I doubt he can even keep count. All of that sense of self-worth that people derive from their career or wealth is lost in the noise of Meta's stock price for him. But winning a board game is tangible. It's right there in front of him, as a direct result of his own actions. He can feel that.

If you couple that with him being surrounded by people who know that losing to him makes him feel good, and that Zuck is more generous when he's happy, you can see why people lose on purpose.
