Previously, one of my biggest pet peeves was the expression "chemical free" with second place going to "organic".
Over time, and as I became more thoughtful about how science is viewed by the average person, I softened. I became more pragmatic. Language exists to communicate ideas. When the meaning of a word or expression becomes commonly used and accepted by a majority in a group, then the definition changes. Holding on to the original meaning is futile and a waste of effort. Only huge amounts of money can force a change in mind share.
That doesn't mean I don't die a little inside when I hear stupid expressions.
"I found it in the last place I looked"
"I could care less"
