I do not know the author of the blog, but this part especially strikes me as a misinterpretation of the point of the piece.

But that's shedding light, and maybe it's not and my interpretation was too narrow.

My interpretation was: Julius is a parasite, who contributes nothing but merely makes the productive members of the team work harder to compensate. He sounds convincing but understands nothing, does nothing, contributes nothing, and not only wastes others' time but also steals their credit.

But you see him as contributing? You see what he brings as being valid and valuable -- is that right?
