Great points. By "act on their own vision" I mean technical vision, the how to solve a problem, not which problem to solve. In my experience this is where many engineers become depressed and want to quit. They're interested in the problems the company is solving, but when implementing solutions they become bogged down in myriad rules with which they do not agree. Coding style is simple enough to adapt to. Having to follow a technology stack, core architecture, and core APIs that you find unintuitive is harder. In fact I'd venture to say (as a corollary of Conway's law) that companies that follow the "everybody writes some of it" style breed narrow monocultures, where everybody sees things roughly the same way.
