Better question, why is this subject being regurgitated?
It's good people should vent and that healthy, and the most important point is that it's Helping Apple to see what people like and consider it, look what happens now many people are using the iPhone 5 5S 6 6S and so why?
Price once when ATT Verizon T Mobil Sprint were subsidies the phone we replaced it very year. now not every one can afford it, no new really reason to upgrade (do you thing face ID is something spacial reason to upgrade ?)so for Apple to listen what people like I think will help them selling more product.
