I can sort of understand that sentiment from Android users. They tend to value control/customization. I've tried Android several times for this reason, because it is compelling. I've always gone back to iOS though, and it's basically just been for a combination of performance and polished UX. My issues with Android were basically:
* Little visual stutters and other relatively minor things bother me more than they should
* High rate of passive battery drain. Android devices seem to typically have much larger batteries, but they chew through power a lot faster when they're not being used than iOS devices. Heavy users probably get better battery life on Android overall, though.
* App quality. This gap is getting smaller and smaller, but it's still noticeable.
* Build quality. iPhones tend to be a lot more durable these days, at least since the iPhone 6 was released. Android devices have been cheaper feeling and more fragile in my experience.
* Bloatware. Most Android devices come with a bunch of shit I don't want and can't easily uninstall.
But all of these things considered, if I was a part of this survey, I would probably have just said something like "I use an iPhone because Android is for poor people" just "for the lulz".
