Choosing your usage battles
Words have specific meanings. Words change. These are both true.
If people start using a word in a way that doesn’t match its established meanings, how should you react? You can say it’s wrong, but eventually it could become so well-established that fighting it is senseless. Sometimes people need a word for a new concept and appropriate an existing one because it’s a good analogy. When vehicles pushed through the air by motors were developed, they needed a name, and people called them “airships” even though they aren’t ships in the usual sense. Before the end of the 19th century, “spaceship” was coined by a similar process.
At the other end, words sometimes get new meanings for stupid or dishonest reasons. For instance, people of certain political persuasions call anyone they disagree with a “fascist,” without reference to the word’s actual, historical meaning. That’s just a smear tactic, and anyone who values precise communication should reject it. “Grooming” is another example of a word that should have a definite meaning but has turned into an undefined smear.
