This is an example of the real world consequences of living in a social bubble. iPhone only makes up 26% of market share globally while Android makes up 73ish% of global market share.

This is such a large difference that it makes the title of the article "Not every user has an iPhone" sound like an insult to its readers intelligence until you realize that author may very well have thought that way themselves at which point you start to question the author.

Because of course "Not every user has an iPhone". In fact, most users use Android, the most popular OS for mobile.
