I wonder how this will work with apples recent fight against online advertisers. If google does track users but it is all anonymous from the advertisers perspective, does that mean Apple is okay with it?
Maybe thats the reason they went back with Google now they didnt want Google to have apple customer data for competitive reason but now that they have a system in place to block that they have gone with the best search engine.
I doubt that google would pay $3B for just anonymous search texts. They must be tracking you.
