That's a propeller... really?
Speaking with my technical illustrators hat on, I would have thought that if you were to create a depiction of a Thing, you would at least look at a real-world example of that Thing, and use that as a basis. I don't know what that new icon is, but it isn't a propeller. Have a look at a real one, then look again at the icon. The old version was at least credible.
Yes, I know, it's only an icon, but surely, why not take the same time and effort that you've put into doing it wrong, and do it right? Meh. The day of the yahoo is upon us.
