Yes, this is a good point. Agreed fully. There's a hint of at least two tenuous causative implications there: if you're successful, you ought to think twice

Yes, this is a good point. Agreed fully. There's a hint of at least two tenuous causative implications there: if you're successful, you ought to think twice before wasting time blogging (ie. blogging by the CEO adds no value to the business). Or the corollary: if you're blogging, chances are you're not yet successful (it's a marker for lack of success). Both are reaching. Blogging by the CEO (founder) simply means that marketing is (also) done by the CEO. The founders and CEOs who don't blog probably delegate marketing activities to specialists (nothing wrong with that). You delegate when you don't possess the skills to execute. This will probably happen when the founders or CEOs don't possess the technical knowledge or expertise about their own fields.
