Just as not everyone (by far) experiences any bothersome issues, let alone ones that are "horrific" or make their devices "unusable" or "ruined" or anything even close to that.
I've seen a handful of people on these forums that will defend Apple against any complaint someone brings up.
I've also seen a handful of those who have complained when iOS 9 first came out that are now complimenting Apple for making improvements and optimizing things.
If I was a new user, I'd take more credibility in the latter handful of peoples opinions.
