His Tweet;
It's quite hilarious. He is the one responsible for ordering the coders what to do, yet he didn't find it necessary to do so. It's not even that hard to do. It would take minimal configuration to accomplish. It literally saves them and their users millions every year. How can this not have any priority?
Bittrex did it like two years ago and that in their glory time as top exchange. If you look at Brian's Twitter you can see how he almost never even mentions Bitcoin. This guy has messed up priorities.
