I never really followed the cancel culture around certain computing terms. I still use the master branch in my personal repositories.
I wonder if it happened for anything other than master/slave, whitelist/blacklist? Nothing else seems to come to mind.
Imagine if people said airplanes need to stop saying retard because that's offensive! For the record, it means to pull the engines back down to idle before touchdown.
Complaining about "cancel culture" is not really any better than complaining about "whitelist"
Language changes over time, and not just for PC reasons.
Keep in mind that language shifts really only work when (almost) everybody goes along with it. When the PC police try to change the language in a top-down manner (and then imply that those who don't agree are bigots), it tends to backfire.
