The outrage doesn't seem overblown to me. For years I knew that my iphones were becoming obsolete not entirely from the passage of time but instead from upgrading the OS. Apple insisted they were not slowing down devices. Now they claim that they started this in iOS 10.2, without notification.
My experience has been that upgrading the OS results in degraded performance 100% of the time. Whether intentional or not Apple would not acknowledge the issue. The phone shutting down at X% charge has always started after an OS upgrade.
