Isn't Google doing the same or less based on only browser data? How does each solution differ in entropy? I didn't get that from Apple's policy page. I am genuinely trying to understand and this isn't a snarky comment.
So Apple can do segmentation aka user tracking at a group level because it doesn't expose the group IDs. Yet, we as consumers don't have transparency into the segments we inhibit. I am not sold that Apple's segment solution truly respects our privacy compared to solutions that don't rely on user identity or store segments.
