The reason for it, as well as the reason for it not being changed, is already explained in Redis' documentation:

https://redis.io/commands/slaveof

> A note about slavery: it's unfortunate that originally the master-slave terminology was picked for databases. When Redis was designed the existing terminology was used without much analysis of alternatives, however a SLAVEOF NO ONE command was added as a freedom message. Instead of changing the terminology, which would require breaking backward compatibility in the API and INFO output, we want to use this page to remind you that slavery is both a crime against humanity today and something that has been perpetuated throughout all human history.
