I believe this is the first time I've ever said this: Mark Zuckerberg is entirely right.
Some in the tech world are in a moral panic about the fact that zillionarie tech baron and Facebook board member Peter Thiel is a major donor to the campaign of the vile Donald Trump. Now, there are many reasons to want to keep as far from possible from Thiel; this is a guy who actually said, way back in 2009, "I no longer believe that freedom and democracy are compatible"and spoke of the extension of the franchise to women as a negative development. He's also one of the founders of Palantir, a primary contractor of the "national security" deep state -- a hell of a thing for a self-described "libertarian" to be involved with. So his politics are awful, contradictory, irrational, and inhumane. In that realm, anyone paying attention concluded "fuck Thiel and the horse he rode in on" long before Trump became the GOP nominee, and his support for Trump is actually kind of low on his list of sins.
But the idea that a company should purge itself of board members based on ideological purity, on political opinions and affiliations outside their corporate role, is exactly the sort of self-sorting and silencing of dissent that is taking us down the spiral of partisanship.
