There’s a critical shortage of housing in Palo Alto (I work there), and small shacks can go for well over $2M. Zuckerberg’s hypocrisy is breathtaking - he is contributing to that housing shortage by denying housing to 4 families while he lectures the Bay Area on the need for affordable housing, all while surrounding himself with a policed perimeter for his property that he thinks the US border should not have.
He’s not denying anybody housing, he’s just making sure the houses built there can’t see in his windows. And vice versa. Really in the end he’s improving the design for everybody.
