I'm late to the thread (had to find it satirized on n-gate.com) but I'm against all conflation/confusion. Against conflating/confusing master (as opposed to copy) with master (as opposed to slave). And especially, since it seems so widespread and dangerous, I'm against conflating/confusing the accurate use of master and slave whether metaphorical or literal, with endorsing slavery of humans, i.e. conflating/confusing the act of merely mentioning with the act of endorsing. Slavery is a thing and we need words to describe and name it; isn't that the whole point of drawing attention to it? Outlawing words actually works counter to the goal. And sometimes we do make computers serve in master or slave roles. They're not sentient so it's fine. Hopefully everybody with half a brain knows the difference between that and doing it to people.
