Condone still means, and always has meant to “look the other way” about something, no? You neither pardon, nor make excuses about something, you know it’s wrong but choose to do nothing about it.
I definitely agree that it’s missused, like my personal pet peeve “begs the question” instead of “raises the question”… lol
It’s funny to see things evolve to a point where we tend to say something like “I don’t condone such behaviour” as way of saying that I don’t support such behaviour, when really you could simply say “I condone that behaviour” and mean that I don’t support such behaviour, but often let it slide.
“I don’t condone” would mean that you don’t let ‘bad behaviour’ slide.
