If you want to make progress in tech, don't let "progress" (in quotations) live rent free in your mind. Focus on actually building stuff.
I hate to use oppression Olympics as an argumentative avenue but I'm a Slav, the word slavery comes from the enSLAVement of Slavic people.
It's often an accurate description of the relationship and even if it's just slightly inefficient, still works great. Why pollute your mind and thought stream with such trivial qualms. Build. Learn. Don't sweat dumb crap.
Same with whitelist / blacklist. From an English perspective these and master/slave have been archetypes for as long as the language has existed. Don't make problems where there are none, and don't TRY to pollute my mind by making me think there are problems, where again there are none. Enough people outside of tech are doing that to the populace.
