Since the deal you mention was part of a lawsuit from the federal government, we actually do know alot about what gets sent between the two companies. The $20 billion a year deal you mention only applies to safari users and ensuring that the default serach engine on apple devices is using Google.com. The deal is far more about controlling competition and denying any potential competitors from being able to cut a deal with apple and thus reach a large volume of highly influential consumers. Im sure there was also value to be found in the search data of users as well, but the deal is mostly anti-competition. There is very little go on beyond general mistrust when it comes to belief that Apple might be selling customer data. Make no mistake, Apple spies on its users almost just as much as other tech companies. The difference looks to be that Apple keeps it all to themselves.
