This changes nothing for a lot of people. Divers, as others have mentioned in these comments as well as in construction/manufacturing (which has a large population of non-white people) it's used in situations where you cannot hear. I doubt anyone's going to convince these folks to change years of acceptable practice on the back of a hoax.

As for the ADL: feed a bear and they will happily take it. Ten minutes of research and they would have seen it's a troll.
