Do you mean you can't take Apple seriously? The article is calling out this issue, not engaging in it.
> I can easily see the number being 99%.
No, it can't. It's utterly impossible for it to be 99% unless it's fake data.
No, it's not. Unbelievably unlikely? For sure.
iPhone has been around for 15 years so there almost isn't a person on this planet who doesn't know (a) what it is, (b) what the competition is and (c) whether it's a right fit for them.
So if you're surveying existing users you're talking to people who knew before they purchased the iPhone that it was going to be a suitable fit for them. So of course the survey is going to be highly biased in favour of a positive rating.
99% is not possible. Nothing on Earth has a 99% satisfaction rating - not even breathing.
If you reflect on it and genuinely believe that 99% seems realistic and even "very likely", well, we'll have to agree to disagree.
