That it's common is not sufficient--the majority is not necessarily right. I think pointing out a historical misunderstanding is worthwhile, especially in a forum with smart people or in an academic setting. Using this expression with a meaning based on a misunderstanding reveals that one wants to sound learned without actually being that, so I do think it's a favor to point it out. Of course it's an uphill battle and there's no hope, but I still think there are enough people who do care about where things come from and using them right.
