being right is more important than being seen as being right
those who say it is "unfair" or "salty" or "ok" or other perjoratives to point out faults in the deeds of others are more concerned with being seen as being right when they clearly are not to the person who is doing the detective work on the evidence of errors
if you have nothing to hide you won't be bothered about people finding your errors, you will thank them
only people with ego problems where they can't face being wrong fight you about this stuff and they are the most important people to investigate and uncover their errors because usually somewhere in the pile you are going to catch them in deliberate error, also known as evil
