I'm going to risk saying this: it's probably because people did not like the new site designer changes they made, now to do a simple task has become very difficult and very complicated, you probably must have realized that this change in the designer is not good and is only creating headaches. on the same day they implemented such a change I read on twitter them many comments from people complaining and threatening to leave the exchange if they did not put the old designer back. so they are losing customers
