Sensitivities during Covid ran high. A lot of things changed then. For instance in the software world removing the name “master” from git usage, and on the TV Show Survivor, the host not saying his famous line “come on in guys”. At the same time pronouns became a huge thing, and these seemingly gender specific or sensitive word terms were targeted.
You are correct, there was a round of this in the 90s or so, where job titles like “waitress”, “stewardess”, “policeman” were all adjusted. I see that as a very different round of language change.
