Anonymized data as a concept has always been a joke. With enough data points, the origin can usually be traced.
The design goal of anonimized data is that it is processed to explicitly disallow tracing. This means not only removing personally identifiable information but also disallow session data.
But the data itself can and does lead to tracking. Personalized online advertising isn't decided by magic.
