Lets take that thought and run with it
“your phone, repair it how you like”. So you repair a security enclave component, say the thumbprint scanner with a Chinese knock-off. It’s half price, and just 2 weeks later your thumb print and Visa card are on the net.
Who do you blame? Why, naturally it’s that “damn Apple”, right? You saved a few bucks and Apple takes hundreds of Millions in lost revenue because they are forced to support bogus components.
Sorry, some things are secure and some things are not. Buy anyone’s battery. Buy anyone’s screen and microphone. Buy anyone’s camera. But if it’s a security enclave component you have little choice; because if you are vulnerable then I am vulnerable.
Agreed. If you fix the phone with lousy parts, who gets blamed when something subtle goes wrong as a result? Apple. So, Apple prevents crappy repairs however possible.
This is a major part of the reason Apple doesn’t sell/license its OS version (MacOS, iOS, tvOS, etc.) to other makers.
The Windows/PC world is the glaring contrast - anyone can build a PC with whatever parts he/she can find at whatever price they find it at - and cobble together a PC - a practically infinite number of parts combinations that are possible with quality ranging from horrid to super-premium and great. Then Microsoft sells an OS that you can (attempt) to run said hardware with. Microsoft attempts to include enough drivers and generic “Universal” software to attempt to cover every one of these possible combinations (and impossible task). Then, most manufacturers of components also provide drivers (often times tragically outdated and unsupported), and often of dubious quality and even sometimes with nefarious code embedded. Users install these drivers when MS’s OS can’t deal with the hardware. More hooks and ties into an OS that may or may not play well together...
And on and on it goes - a never-ending battle that the “average” PC user has no patience for or desire to deal with.
Or Apple’s contrasting model: they make the hardware, so the component combinations are FAR more predictable because they have hand selected/specified those components. They know what they are dealing with. They set the driver rules. They set the compatibility thresholds. And then they develop the OS to fit that integrated select set of hardware. The positives are - consistently less compatibility issues and software conflicts, and overall far more reliable function (the industry leader, despite very vocal minority of dissatisfied users). Further - a much longer usable life to the hardware produced by Apple because of this drastically limited set of hardware combinations.
But its all a trade-off - users are somewhat limited in what they can customize and upgrade.
I prefer to spend my time in more productive endeavors than tinkering and trying to kludge things into working. I don’t have the time to tinker (that was my hobby as a youngster). I want things to just work, and I want to get maximum life/use out of what I invest in. Apple provides that.
