I think it's very often repeated that the hardest thing about growing a business is keeping the culture, and it's simply impossible past a certain size unless you literally develop a cult of personality like Jobs or to a lesser extent Musk. Extremely few manage to do it. And when the culture goes, that's what you get: least effort. And the least effort is to do what you're saying, "just do more of the same, but bigger, or with a hint of chocolate".

At least in most of the modern world. I think this effect is a _little_ weaker in China. It definitely used to be much weaker in the West too, at some point in time. But individualism, cultural capture by big capital, yaddah yaddah.
