To piggyback, there's an additional difference between being a public-facing CEO of, say, McDonald's, Exxon or Apple, and being the public-facing CEO of a non-profit which exists due to the donations of primarily liberal and libertarian internet people. The prior case might cost them a little revenue due to boycotts but if the person's effective, you can make a case for 'private views' and 'shareholder value'. When your whole company is an activist platform, it's a bit harder to say that political positions of the CEO don't matter.
