Yes. I guess Musk is the exception proving the rule.

Of course, exceptions don’t prove rules, they disprove them. Maybe Musk is showing that CEOs could say a lot more than they choose to, at least if they have charisma. And run certain kinds of businesses, appealing to a certain kind of investors and customers.

It's a reference to a popular saying: https://en.wikipedia.org/wiki/Exception_that_proves_the_rule

The logic of which is, if something is an exception or so exceptional that it's called out as an exception, that implies the existence of a rule.

I just think it’s sometimes used when it shouldn’t be.

Well i think in your case you’re the exception proving the rule

I’m off to the island of misfit toys. :-(
