Nah, I don’t judge people for being wrong or inaccurate, particularly when the colloquial use of a term is as firmly established. Ideally, people would still know the distinction, and I’d prefer to have journalists be accurate at least, but mostly I care about knowing what’s technically correct myself. I don’t need to be a pedant, I just don’t want to be ignorant.
