Comment 1 for bug 1202040

I agree these icons doesn't really match the overall style and could be replaced with something more fitting.

I'm not a copyright laywer and I only learned about this recently, but it turns out different countries deal with public domain differently, and in some it is rather hard/impossible to put a piece of work in the public domain [1]. So we probably want to sort that out regardless.
