This has always been such a funny argument to me. The "some" is carrying some much weight. Yeah there's a couple vocal apple users in hacker news that think a closed ecosystem is good, more private and secure, they trust Apple and they indeed have chosen the iPhone for this reason.

But more likely than not, people choose iPhone because everyone has an iPhone. People choose iPhone because when both parents have iPhones they buy their kids iPhones and then when their kids grow into young adults, well, they're already invested in the ecosystem to such a degree that it's impossible to get out.

More likely than not, they choose iPhone because iPhones are just what people think about when they think smartphone. Because Samsung phones seem "complicated".

I really doubt people even care about privacy and security. I mean, sure, if you ask them if they care they will say yes; because that's how polls work, no one wants to say they don't care and be judged. But if you were to ask people "why iPhone" I'd say the answer will be more on the lines of "because iPhone".

The modern world is made on marketing and Apple is the best company in the world at it.
