There is a difference between a public figure and a CEO.

Partially agree. But a dumb CEO can be replaced (see Sonos).

Again, why should I care? The company does not only consist of the CEO, which is also why I‘m interested in the things a company does, and not what a CEO says.

People have private lifes. CEO‘s too. I don’t see why I should remotely care what the personal opinion of a CEO is. And I am deeply concerned that this is such a big deal, no matter what their opinion is.

If you have a personal problem with that, that‘s totally okay. Putting them on a stand, is not okay. Let them have an opinion. Debate if you disagree. But stop making such a scene out of everything.
