There's a quite a few false positives in that list (e.g. a person named "slavek" always using his name in branch names), a few references to the "master/slave" analogy, and browsing the first few pages I keep seeing the same usernames over and over again (mostly from what seem to be non-native English speakers).
So the number seems much lower than 4000, and mostly the result from a very small group of people. I don't know how many branches there are in GitHub, but this seems like a very very small percentage.
Replaced with what, though? Nobody talking about "slave" seems to notice that "servant" and "robot" have similar baggage despite different linguistic roots.

As I sometimes say, I've been Black my entire 50+ years on the planet. I've never met another Black person (or anyone regardless of their race or ethnicity) that felt that robot has “similar baggage” to the word slave.
With a glorious newspeak that greatly improves on the legacy language by simplifying the grammar and adding safety mechanisms to ensure all conversations are safe spaces.
