I've never understood this idea. You might pay for AppX but if they use data provided from LibraryY, nothing outside the privacy policy and license agreement gives you any idea (much less control) Iver what LibraryY does, regardless how much you paid for AppX. Paying isn't enough, you must read and understand these agreements enough to know that most of the time "we partner with certain 3rd parties and your usage of those third party libraries are governed by their license agreement and privacy policies" type wording is all you get besides a big old middle finger.
