There’s also the possibility of having genuinely good intent, but still speaking entirely from your own conjecture of what might make others uncomfortable.
Ultimately, you should always talk to the people actually affected and take action based on that. But anyone can and should start the initiative when they think something is harmful.
The original audio after mastering is also still called a master, but I haven’t seen anyone complain about that. And that (as well as the same meaning for other media) is the word that the branch name master came from, so etymology can’t really be an argument there (though I also think etymology is terrible reasoning for renaming something in general).
