Due to how human voting behavior sort of deviates from the spirit of HN, it's a good excuse to have some people moderate the site as having an emotional mob control everything could have the entire site turn into reddit. The problem is the people moderating the site are also human and also victims of their own biases and business interests so you get hella sketchy stuff like this pinned post.
Still it's sorta good that this post wasn't outright deleted.
