So we're moving the goal posts from "these features can coexist" to "such a phone has to be popular"? Why don't you skip to the end and tell me where they're going to end up?

If phones are not for sale with features, how does that allow drawing any conclusion about popularity? I've yet to meet a single person who says, "I sure am glad I can't use fingerprint unlock on my iPhone", but obviously it's not worth leaving the entire ecosystem

Recall also that Android manufacturers compete so ruthlessly with each other that they barely make any money
