Exactly what I was going to say. I don't use iPhone because, well, it's iPhone. And until, like, this year, it was strictly more prohibitive than Android. Also, it was honestly just worse of a device than some Android flagships, and the tradeoff is only worth it if you are a lazy USA-ian, who doesn't use any "sketchier" non-mainstream apps, has an Apple account and owns a bunch of Apple devices anyway. Oh, and all your friends use iPhone Messages app. Then iPhone is the default. But outside of USA it was always more of a gimmick than a natural choice.

That being said, even if you wouldn't have said it before me, I probably shouldn't have said it too anyway, because I suspect that globally speaking the GP is right. Most people don't buy flagships, yet everybody has a phone. And Apple doesn't even try to compete in "non-premium" market, it's strictly impossible to buy a new iPhone for the price of some Redmi or whatever, which isn't even noticeably worse than an iPhone, practically speaking.
