For those not familiar with that term like me, Wikipedia:

> "Virtue signalling" is a pejorative neologism for the conspicuous expression of moral values, when performed to make oneself look virtuous to others.

It's not. This is more like a swear word. No one would expect that calling it the "fuck" branch would be OK. Just because more people are OK with "master" doesn't change the fact that it bothers other people who are just trying to code. This isn't hard to understand.
