It also looks like the post got a fair number of downvotes, and that its karma is way lower than for other posts by the same author or on similar topics. So it actually seems to me the karma system is working well in that case.
That’s what I thought as well. The top critical comment also has more karma than the top level post, which I have always considered to be functionally equivalent to a top level post being below par.
