Huh? Apple potentially has everything on the device, just as Microsoft does. Maybe they don't touch it, at least intentionally, out of respect (or just prudence). But if I recall correctly, they accidentally logged all Safari URLs for a while.
Safari shares the same url/search bar, but I have not read their license. Would be pretty surprised if they are not logging all URLs.
Which is true. They don't sell the data because they directly monetize it. Same with Google. Google didn't just start doing that one day, that's been their business model since they started doing ads. Apple's business model is selling users devices, which they would jeopardize if they tried to also sell their users' data.
How can you trust a single point of failure to "do no evil"?
