I think you'll find that view in any smoothly-running business with an eye on the future - not just large corporations. Unless the management are the devs.

We have to specialise at some point - not everybody that gets hired is going to be an ace industrial strategist. Few devs know how to qualify a sales prospect. If you have such people in management, then as a dev I don't want to do their job for them; they should set strategy and find good customers.

I guess we all have differing perspectives on this kind of thing; one's perspective is partly formed by one's experiences.

I'm not talking about startups - I never worked in one. But I've worked for quite a few companies with < 20 staff.
