When you see "sponsored" on a listing, that doesn't tell you how much the vendor paid. Also many large and reputable vendors will pay simply to guarantee they are at the top of the listing. For the vendors that don't sponsor, you don't know whether the amount they save goes into a higher quality product > This is essentially using user-data outside of the intent it was given and that should be controllable by the user and default to the most conservative option without annoying dialogue boxes or other harassment. Except feeding user data back into the system makes certain things technically possible that weren't possible before. Do you think modern map applications would have the same degree of accuracy if they weren't able to use user data to improve it? > Whether it's within the platform or not shouldn't make a difference. It does make a difference because keeping it within the platform could be used to improve the platform itself. Sending it outside the platform could be used for more malicious purposes. In the map application example, the user knows their data feeds into improved accuracy. But they don't know where that data goes outside the platform
