If I post something on my personal blog, and it's against the company's Code of Conduct, then I'm in trouble with HR. If I'm the company's CEO, then I'm in trouble with the board. You're not an island.

Then you'll just have to be a CEO with a platform. And if it's on your personal blog, I don't see why you'd be in trouble with HR at any good company, unless they're monitoring your communications.
