Think about the type of people that use Pinterest and you have your answer as to why they never get any ire for the decisions that they make and why their user base is seemingly OK with it.hahaha.
Real talk: the most proactive social network that never gets talked about is Pinterest. They out there doing the lord's work on this front, shadow banning all kinds of hateful content, ridiculous anti-vax type content, etc. If you ever go to any Pinterest related event (something I've done for work), upon sign up you're given a slew of pronoun options to choose from after entering your name. I don't mean just the they / them / their variety.... ve / ver / vis; xe / xem /xir; per / per /pers; ze (zie) / hir / hir.
I literally learned about gender neutral pronouns from a social network that is actively trying to be inclusive and minimize hate. Kind of wild.
