Turns out it is:
> This term came from Bitkeeper, a predecessor to Git. Bitkeeper referred to the source of truth as the "master repository" and other copies as "slave repositories".

Otherwise, one would probably soon need a list of banned words that may have been used in the past in "controversial" context so to not offend anyone. But I'm not sure how much of human language will remain at this point.

https://en.wikipedia.org/wiki/Master%27s_degree
A master's degree[note 1] (from Latin magister) is an academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice.
The holders of a Master's degree are expected to be the "source of truth", as much as git's master branch is the "source of truth".
