You have the word "master". It has at least two meanings in standard English and an additional one for technical jargon. Let's call these concepts owner/slave, expert/apprentice, and primary/secondary.
Even though owner/slave and primary/secondary are different concepts, the technical jargon makes the unfortunate reference the owner/slave meaning because of the use of the word "slave". It's difficult to defense the use of master/slave in this context.
The master in the expert/apprentice concept could be called leader, expert, or teacher and no one would have a problem with that.
This distinction is where people start getting upset.
I'd argue most technical people didn't even give a second thought to master/slave and for them they never considered it to be anything other than primary/secondary because owner/slave is no longer common use and hasn't been for a while. Besides, US Civil War was more than 150 years ago! Who gives a shit?
Well... people do because the effects of that war still affect our society and no one agrees on how to fix it. Removing problematic phrasing from our language as part of that makes sense. No one agrees on that either.
