Apple products are an acquired "taste"
Their end to end business model rubs some people the wrong way, me for one, lol, just because I have dealt with older companies that had the same end to end model and it was always a pain when sourcing parts or solutions
What end to end means is that a companies product is made in a way that it only works well with that companies other products
iPhones Bluetooth can be an issue, because Apple doesn't own bluetooth, so would prefer if people didn't use it
They were stuck with WiFi but still don't like it
If Apple makes a product like wireless headphones then it will make sure other brands wireless headphones have issues connecting to an iPhone, just little irritations, so when there is a complaint they can suggest trying Apple headphones, and then laying the blame on the "poor quality" of other brands headphones, its not true but what can you do about it, not a thing
Its not a "bad" thing for the company, just the consumer, because the company can say they are doing it because of security control or quality control, they want end to end compatibility, which is not a "bad" thing
It would be like having to use a Ford 12volt battery in your Ford car or truck, some would only use a Ford Battery and be happy about that
Others may want another brand, but it would only start the engine 9 out of 10 times, because its not a Ford Battery, an irritation, and it would eventually start, complaint would be answered by "have your tried a Ford battery?"
Yes, ridicules example, but the point is valid
I think APPLE makes good products, just don't like what comes with them
