For those on iPhones or respectable mobile network operators, not everyone has as good of an experience as you do.

For people who buy subsidized Android-based phones from some carriers such as Metro by T-Mobile USA, they either come with bloatware baked in or they download the bloatware when you first activate the device or something like that.

These things are fairly easy to disable if you know what you are doing but if you don't know what you are doing, I can imagine people will simply put up with ads showing up every time you pick up the phone. It can get annoying VERY quickly.
