The comment in particular that the OP is responding to is this one, from the comments section on the blog:
>>“representing the work of a designer requires a shift in culture of the dev team”
>BS. A gigantic and stinking pile of BS.
>Becoming _part_ of a dev team requires a shift in culture *of the designed*.
>Designers should stop thinking that they lead or guide the dev team. Make your _proposals_ in a >humble and collaborative language and you will be heard, like everybody else. Try to impose your >“vision” from high in the sky and you will be… ignored. It’s that simple.
This comment seems to match the thinking of the OP. It asserts that designers should not bring their professional knowledge to the dev team, should not bring vision or guidance but should instead be humble in the presence of developers. I don't know whether this is supposed to be sexist or elitist but it's not a successful collaboration strategy.
