>>anyone buying an iPhone 14 is only likely to do so from Apple 25% of the time<<
25% is about 44 million iPhones or in the ballpark of 40 billion in iPhone revenue. I don’t think “how FEW people buy iPhones from Apple” is accurate. I’m surprised Amazon has not tried to get in on it.
>> All of this is particularly interesting given Apple's love-hate relationship with carriers. Apple famously doesn't allow carriers to install their bloatware on iPhones, whereas Android phones are often full of it<<
Now ‘Full of it’ seems more accurate

. Regardless, bloatware is one of those oft unmentioned but yet another IPhone advantage.
