I see it different, for many founders, companies are a way for a personal grow. In that case founders grow with the company and change their management styles. Ballmer was a very early Microsoft employee, he was even in the IBM/DOS license negotiation.
You're completely right on the growth aspect. If you're working somewhere with a founder and their not growing in that way while the company is, I can see nothing but headaches. The original link essentially calls this out... what you did at 5 people doesn't work at 50, which doesn't work at 150, and on. You gotta learn and adjust; as it scales up, the folks who help move beyond the Founder and into a trusted group.
