The first two do not have low latency high bandwidth connections (or often any connection at all) to the user to collect data, so it's not a reasonable comparison. As for the third, I understand that duck.com claims this, but I don't buy their claims, considering their behavior. None of these sites that claim to not collect user data should be trusted until they submit to a transparent audit that exposes all their infrastructure. As for the fourth, this is a tiny exception to the rule held up by some individual with standards.

Apple doesn't fit the pattern of any of your examples.
