From everything I've heard, Apple's org structure is a lot more focused and UX-driven from the top down than basically any other large tech company. That means you get a lot less compromising and in-fighting.
The other side is how Apple makes money compared to other companies. Meta makes money mostly by selling you (the user) to advertisers (the real customers). Same with Google (70%ish ad revenue). Microsoft is a hot mess of competing B2B fiefdoms (the vast majority of their revenue comes from businesses, not consumers). Amazon only makes a few products directly for consumers, and mostly makes money from being a marketplace + AWS. That leaves Apple fairly uniquely positioned as a premium consumer hardware company that also sells consumer software services to enhance the experience and... drive more hardware sales.
Apple builds an insanely strong core from which any and all other teams can (maybe must) build on top of and use to power their team's platform.
You have a core messages team for example - off of which Mac, iPhone, and Apple Watch teams integrate. Do that for each core service or product (photos, safari, notes, music, etc).
The Amazon structure is such that everything flows from the person above you, work is not shared between teams.
One is compositional (Apple). The other is inheritance (Amazon).
On the face of it, it sounds like a company would want coherency, but in practice it means leaving a lot of money on the table for every single of your products. Any consistent design decisions means anyone who's not pleased by it has no option in your lineup to go to. That's of course a gamble Apple is willing to take.
For instance, Apple consistently uses glass and metal in their product design, the only exception I can think of being airpods and their mouse. I personally prefered the plastic for weight and comfort, so that set me out of the market for their headphones and I went to Sony for instance.
Same for laptops with touchscreens, if you care any bit about them Apple is a no go to you. Same for so many things.
PS: on inconsitencies and incoherencies, Windows is the king of the kitchen sink approach, and it's consistently stayed ahead of Apple in numbers. Another instance on how being opiniated isn't only a positive aspect from a business perspective.
Yes there also will be quirks I'll be unhappy with, which I _could_ (given enough time and experimentations) find a better solution for. But fundamentally I'll be getting a solid product, that works well enough. It is _that_ promise, which fundamentally allows Apple to do an online store and do a mostly directly-to-customer retail operation.
If you increase diversity, you make this "buy any product and you'll be fine" thing so much more complicated, loosing more sales than the niches even contain. I'd guess almost all people just want it to work :TM:, at least that's me, and that's me deciding the phone of my mum
On the other hand, that doesn't seem to be what most consumers long for. Apple had two runaway successes with the iPod and then the iPhone, but to note, the iPhone is not the best selling phone brand nor dominates the international market. Same way Apple is not the #1 computer maker.
So yes, focus and consistency brings tremendous value, but there are many other ways to get that level of value, and many customers will have different priorities.
(I also don't think any brands need to be #1, being profitable should be enough, but I am more and more interested by how Windows has stayed at the top for so many years. In particular Apple progressively feels closer to Sony when it was at its peak: superbe products, strong ecosystem binging, coupled with also a heavy dose of strategy tax on how to benefit from what the other companies are doing)
