I think Steve truly believed at his core, very simply: your laptop is your diary, and they have a responsibility to that. I don't think Tim would be CEO if he didn't believe what Steve did. It's so weird, but I really miss Steve. https://www.youtube.com/watch?v=Ij-jlF98SzA
As someone who builds industrial/scientific machines, the consumer oriented devices that Apple makes are completely unusable for me. Locking down completely capable computing devices seems like such a waste. I'm also not a fan of how Apple controls devices and the market of software after the device has changed owner. I'm staying the hell away from this ecosystem. Not sure why many so-called "hackers" are so enthusia…
That being said, I love iOS on my phone and tablet. I used to prefer android, because of how much I could customize it, but it slowly became less reliable and more centered around selling me products and services sponsored by Google or my carrier. I switched to an iPhone and iPad about 7 years ago and am much happier with a reliable set of mobile devices that I know are relatively secure and wont get in the way of what I want to do.
Point being, the OS you want on, and ecosystem you want around your devices absolutely depends entirely on what you want your devices to do (or not do against your will).
