I once had a discussion with a coworker at a major company known for its app, where I was complaining about an Android bug and he genuinely asked "does anybody even use Android?" And I responded, "only the majority of users in every country around the world including the US. It's even 50/50 on our app!" Afterward, I found the internal numbers for employee use of the app was 96/4 in favor of iOS, and this included employees outside of tech and outside the US!

He, like so many others, was totally oblivious living in the Bay Area tech bubble.
