Dear, it was a bug and not a change like everyone assumed it was. If it really was a change, we would be stuck with it for all eternity. No matter how much people complained or whined about it. They don't give a shet if we hate changes or not.
Don't be so naive, Google/Youtube does not care about us users, only about the users that make it money. They have made it blatantly obvious since the beginning on 2012.
