Now it was a while ago I left the Apple ecosystem as it became clear they didn't actually care about UX anymore, but did "strong feedback during beta-testing" ever actually result in any results? I remember doing something similar back in 2012-2013 sometime, and friends having similar feelings across the years, that it makes me think that Apple never really did any changes based on feedback receiving during the beta testing.
Has anyone here ever written something in via the traditional feedback forms/venues and actually had something changed before the final release? I even asked around my circle of acquaintances and even the ones 110% into the Apple ecosystem seem to never have noticed anything changed based on their feedback.
