It's certainly not like "expressing public support for sports teams". It's useful information: you're gonna reference people with pronouns.
I don't know exactly what feature they were turning on and off. Most programs let you type whatever name you want, and adding your pronouns to it is trivial. (It helps that they're usually short and don't take up a lot of real estate.)
