All of what you're written appears to be based on instinct and blind prejudice. Apple Music has 11 million subscribers, thats 10 million more than Spotify - though I love and hate both equally. Not even device Apple sell has to be iPhone success, in fact that would mean they're making watered down mainstream crap for the masses, very few things that are the most popular are the best - Apple needs more niche products for techies, not to stop making things and only concentrate on the iPhone because it makes the most money, if you're wishing profit over products then that would be a very sad day - my Apple Watch is a far more enjoyable product than my iPad has ever been.
The rest of what you say is opinion, but since iOS became "user unfriendly" sales have sky rocketed. Its a hell of a lot more simple for the average user than most Android skins and there's no way in hell id want to roll back the dated Forstall led design.
