If internal documents from Apple showed that Dev's were allowed to release code that performed badly, but only at certain times of the release cycle, that news would be huge.
Comparing to Samsung is just a joke - how often do android users even get the choice to update, not to mention how Samsung releases may or may not match up with Google (Android) ones.
Apple users don't have that problem, and they use the same phone companies.
If Samsung agrees to let the networks dictate when updates will be released, that is their fault.
Android releases are not generally available at a consistent time. Apple marches software release in lock-step with hardware release.
When you write an article citing a "study" based on a spike of Google searches, the Android based metrics will be more spread out because implementation of the new software is more spread out. A "study" should control for that sort of variance.
