QT WolfieChristl: When the data industry is talking about sharing 'anonymized' profile data:
They do indeed not share email addresses, for example. But they share hashed versions of it, and they all use THE SAME hash function, and can thus still monitor and act on people across the digital world.
In USA they make same with hash of credit card number and phone number since minimum 5 years to track customer anywhere.
