Not "political opinions," but "active participation in political movements."

And do you think tech is somehow exempt from this? It's hardly uncommon for CEOs to be subject to pressure because of their political views; doubly so in situations like this where they perform a significant non-commercial role.

So I'm actually pretty happy that CEOs are subject to public scrutiny.

It's interesting that you use the euphemism "political opinion" for oppression. The reason this was an issue for Mozilla was not because people have strongly held views on carbon permits vs. carbon taxes but because Eich went out of his way to help take rights away from an already oppressed group. This is truly disgusting behavior that many people (not just gays) rightfully wanted to distance themselves from. The fact that Mozilla draws most of its contributors from progressive engineers put the organization on the brink of an existential crisis, which is more than Eich could overcome with any of his technical plans as CEO, no matter how well thought out those technical plans might be. He had to fix that situation by admitting he was wrong. He didn't, making him an unsuitable CEO.
