In all areas of life we judge those around us not by the true facts, but on our limited knowledge. Working to improve that knowledge can result in a change in judgment. It seems completely reasonable for there to be a person who does good work but who isn't know for doing such, and as such is viewed worse than they should be. By working to increase the knowledge of the work they do, their evaluation in the eyes of others will improve.
Of course, it isn't a straight forward or simple in practice. There are those who lie and misrepresent, and if you are to obvious about your intent you will be viewed as manipulative.
I don't see why this deserves either the label of BS or a ban from HN?
Perhaps some thing think it's uncomfortably close to the 'slur' of 'virtue signalling' that people throw around. While I'm sure the intention was nothing but pure in how it was used here, it did make bit second-read the comment to assess whether it was being used in a negative way, and to really understand the point being put across.
