It's amazing that all those other companies have not figured out that their apps are generally bloat, and they release all sorts of models to Apple's fairly tight lineup.

The winning example of tight product management is right there for them, but they continue to act like 'feature factories' without any concious 'whole product' design philosophy.

Probably many people within these organizations are aware, but they don't have the power to resist ingrained operational culture.

There is a possible winning strategy in trying to cover bases Apple isn’t interested in. Apple has shown that they’ll make phones that seem to be successful to some degree (the mini) but just aren’t successful enough by whatever internal metric Apple is using. And there are some things they just don’t have right now like foldable phones.

(I’m aware of the rumors)

That doesn’t mean you can’t go overboard. I don’t know Samsung’s current lineup, but I think we’ve all seen PC manufacturers who make 75 different models that are all just ever so slightly different for seemingly no reason.
