Yes, Apple fans seem to be forgetting that the ones in power at Apple are business people, who care as much about customers as any other company. And being business people they don't have sympathy for developers either and in fact would rather see their power reduced. In their best scenario, all developers become low-wage employees but without the benefit of employees. A bit like Uber drivers.
You can't sell $10,000 Mac Pros and $6,000 displays with a neutered operating system. Nobody is buying the 16" MacBook Pro if they can only buy apps in the App Store. Overnight they would lose pretty much every (non-iOS) developer, most video editors, every podcaster and audio engineer, most photographers, every single scientist, most engineers, mathematicians, and many artists...
That would be an absolutely fantastic pitch in a management meeting. Who is left, accountants... teachers? A few schools?
Not only would this be a massive hit to the Mac... likely lethal, it would also be a massive blow to iOS. Because much like every other developer on the planet iOS developers lean heavily on tools which cannot ever be found in the App Store like git, Python, Ruby (required for CocoaPods), and a million other Unix tools.
This has to be one of the most bone-headed, yet commonly repeated bits of anti-Mac nonsense out there.
There is zero reason Apple would do what you suggest. You haven’t provided one, you just assume if you utter the phrase “Business Sense” enough that people will agree with you.
shrug
There is zero sense or logic in these assertions, business or otherwise. It’s baseless nonsense.
