No, they're mad because they were sold the benefits of vertical integration, tight control, limited options etc leading to better user experience albeit at higher prices. The better user experience part is not holding up in recent reality and people are rightfully dissatisfied.

You've to remember people pay premium prices for Apple stuff. If I buy a $300 Moto whatever I'm much less inclined to complain if it breaks vs when I'm buying a $800+ iDevice.
