I have a feeling the usual "just have a thicker skin / ignore it" retort goes right back to the article's point.

People who are predisposed to having/developing a good "filter" suffer from false consensus effect (and in the case of internet personas, survivorship bias) that leaves them somewhat baffled as to why others don't-Just do whatever they do.

Like picking espresso machines and hiring/training employees, or "raw-dogging" long distance flights, successfully handling the vitriol of a tide of internet people hurling vitriol (whether it's someone's bad day or they're just crazy, tilting at windmills or containing a kernel of valid criticism) is highly personality-dependent in a way that many cannot just will themselves into powering through it every day forever (and will be absolutely miserable if they put themselves in a position where they have to).
