Sounds to me like Apple didn't factor the degradation of battery into the design of the phone and instead focused solely on their relentless push for thinness.
All modern batteries degrade past the point of usefulness. It doesn't matter how big the battery is if you leave it in the Sun long enough it will die. The question is, "what then?"
Many people are reasonably asking that they be made aware of the problem instead of quietly kneecapping the phone.
