I feel the same way, and it’s depressing that people have to risk their reputation over this. If this was about people waving confederate flags or holding Nazi banners, we should do our best to keep those people out because these are symbols of ill intent used to send a clear message of hate towards minorities. But I have never seen people use the noun “master” as a symbol to spread hate. Moreover, I don’t think many people have even thought of slavery when referring to “master” in CS context before it was brought up in this manner.
But all this aside, this would’ve been a no-brainer if renaming the default branch didn’t have other real-world consequences. If it has a possible chance of making people happy, we should by all means do so. However, the proposed change is inevitably going to break many scripts out there that manipulate git repositories and forces additional work for countless people all over the industry. At this point, I think it’s reasonable to rethink whether this is actually going to improve the lives of anyone at all before proceeding.
