Indeed, fears about deanonymization are a reaction to three structural shifts: the cost of analysis has plummeted, the volume of stored data has increased dramatically, and models have become better at identifying patterns that humans miss, making it impossible for interested parties not to take advantage of this. But the conclusion isn't that "anonymity is dead." The conclusion is that anonymity is no longer a guaranteed technical property. It's becoming a behavioral skill that can be developed.
