Why are low standards for dps acceptable?

[Reilyn]

And the fact of the matter is that if your dps sucks in FFXIV, we know. We just can't say it out loud.

... for the fear of being reported and banned because 3rd party program use, and antagonizing the player (even if you didn't mean to, people will report you to get you banned if you so much as sneeze in the general direction of their feelings to hurt them).

Yet WoW had damage meters for ~10 years, and that driven alot of people to not suck at their class because everyone will know, and they know they would be called out on it. That alone created drive to make people want to get better.
