Earlier quoted context omitted.
Some customers buy into the Apple ecosystem because of its walled garden. Not despite of it.
Really? Who?
I buy Apple products not because it's a walled garden per se, but because it's Apple's walled garden. Apple has been the only vendor to provide me with a consistently top-quality user experience, so I trust them to make decisions that benefit me. I don't have the same trust relationship with other software and hardware vendors, so their walled gardens I would protest against.
