the value of personal data can only be quantified if you can follow the path to its eventual sale. If they are not selling it but using to expand their own presence I have no issue. However buyers should be easy to identify along with the transaction value.
i just find it odd government and some who don't like what these companies put so much value into this data when the vast majority really assign it no value. people willfully give up so much and its not going to change because people want to be noticed more than they want to notice others
