I was about to write that too. I'm not quite sure if I find the change necessary - but who am I to raise my word against it. I'm a white guy, it is obvious why master/slave has negative connotations and that's enough for me to let them decide.
I just listened to a podcast about "whiteness studies" maybe that enforced my opinion on this - but why would I - a white guy - would want to criticize this discussion. Be open, be welcome, accept diversity is a main rule in many projects. Why would I not want to change something that others consider harmful(especially something as simple as wording)
