In our own industry, too, "master/slave" being gradually replaced by "primary/replica", "primary/secondary", etc. There was a lot of similar red-top-style complaining about "political correctness gone mad!" in the early days of that change, too.

My days of talking about "whitelists" and "blacklists", modulo the occasional slip as I start modifying my lexical habit, are done.
