First off the notch is simply terrible design. Companies began copying Apple because they did it first and when Jobs was around, it was a safe bet to copy. But there's absolutely no way he would have ever launched the iPhone with a notch if he was around. How you know the notch is terrible is because no one ever said "this is a great design"...all you ever hear folks say is "I don't mind it" or "I got used to it".
Second, a lot of folks don't use a front facing camera or do so very rarely so it's a perfect solution for many who have no interest in selfies. Yes a new mechanical failure possibility is there but worth the solid and beautiful design of the phone.
