Every part of this is wrong. But the "notch trend" bit is hilarious. The idea that the notch is a "trend" Apple started on purpose, rather than a design element that was necessitated by making a full-screen phone that still needs to have 9 sensors and devices pointing forwards is laughable enough, but the idea that Apple would refuse to implement another design because of the "notch trend" is full-on goofy. Apple doesn't think or work that way.

If you increased the effective resolution the touch targets would get very hard to use.

I don’t think the notch is a factor in this.

Apple knows how many they sell. I’m guessing their sales metrics show it’s just a tiny tiny portion of sales. The fact it’s no longer similar to other phones they’re still selling means the economy of scale isn’t there anymore.
