I think this is a genuinely interesting point, and I wish that we as a society had a more nuanced discussion about what that right is. AdTech is largely anonymous in the same way that crypto / web3 is anonymous - it shuttles around cookies / identifiers, but largely does NOT care about any information that is actually personally identifying. If the laws were regulating storage / transmission of information that is actually personally-identifying (addresses, emails, names, etc), that would be much more reasonable in my mind.
