I think the original article is predicated on the notion of "management" as a role (specific person so designated), and not a skill, that can be taken up by any developer. If it was the latter then the whole argument would fall apart.

Personally, I think managers are primarily intermediaries between capitalists and laborers. So they are needed under capitalist mode of production, where surplus value is extracted (according to Marx, at least), but they are probably superfluous under different modes of production, like that of open-source software.
