I think the grandparent post's application of quotation marks around "BS" subtly speaks volumes, i.e. perception of the bullshit value of a job is potentially invalid. Marco's essay reads as if he's got a pretty unilateral opinion about the worth of things. A person is allowed to deem something BS, but they've got to be open to potential compromise.

Apparently someone once thought over-designing the O-rings on the shuttle was BS work.
