3. Every other app has to ask user to "opt in", default is "opt out" while for apples own prompt the user has to "opt out", default is "opt in". This alone is evidence they are not subject to the same restrictions.

My bet is that the Stocks app says the same thing, and that people are confusing OS data collection permissions with app data collection permissions.Is that a meaningful distinction? "Oh, yes, we _do_ collect data from you, but have no fear, it's from the OS, not from an app!"
Either way, data is collected.
It may be an Apple problem regardless, but OS settings about data collection do not control app settings about data collection. Should the apps have those data collection settings? Certainly. But now you’re getting into something that Apple would be building that you can guaran-damn-tee that they will force other applications to implement (because it’s good for the user).
