I have no desire to defend people's linguistic games that were extremely low value. I do not think these games pass a cost benefit calculation. But fighting against these memes also doesn't pass a cost benefit calculation.
Having said all that, turning a plane around is a meaningfully larger cost on everyone involved than having a commit/merge hook that tells you to rename a variable.
Engineers still say blacklist, even though I avoid it in my own communications, it's not the end of the world.
