You apply the word "hate" indiscriminately to the point you appear to like interjecting that word into discussions where it is not warranted. Try dislike, appalled, dissatisfied, upset.
Personally, I have owned most iPhone models since the 3.
I am appalled at what iOS has become. Hate? No.
But honestly, if you're appalled, why continue? Asking, not trolling. My threshold of change is a lot lower than that.
