FWIW, I worked at MSFT and had opportunities with both Gates and Ballmer. I can absolutely ensure you management teams existed at the company. Hell, Microsoft is made of layers upon layers of management teams. A young, bright-eyed version of myself thought this was inefficient (and it was to some extent). But I got a chance once to ask Ballmer what a typical week was like for him--holy hell, managing an organization of 90k+ employees is not a challenge that many of us are made out for.
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.
