Well, they can buy an Android, thus I think they have chosen.

I like Apple's walled garden. I'm a developer for 20 years professionally and 10 more as a hobby. Writing this on a MacBook Pro, with an Apple Watch on my wrist and my iPhone next to me (I left the iPad at home).

I care that Apple's has this control over their ecosystem that I feel 100% confident on leaving my iPhone or iPad with my kid and know he won't follow some weird website instructions and brick/compromise it for example.
