It's somewhat unfortunate the label is also applied to CRUD websites and mobile applications,

These websites and applications can still have vast security implications depending on what kind of data is being collected.

The advertising industry has done security a huge disfavor by collecting every bit of data they can about everyones actions all the time. Adding some ad library to your website or app now could turn it into a full time tracking device. And phone manufactures like Google don't want this to change as the more information they get, the more ads they can stuff in your face.
