I am once again happy that the EU is fighting practices like these via legislation.
Some outcomes can be annoying, but the net result is still positive, for the consumers and their data privacy at least.

  The adtech/data broker business is still very lively in EU. The last time I read into it a year or two ago the consensus seemed to be the privacy gains over the last decade have been modest at best. There was a few big name trackers that were forced to narrow data collection but the general ad/location tracking and data broker business is still mostly the same.

    Do the big guys sell to the small guys? Like if I'm a shady small company trying to buy as much information as I can about a certain user, will I freely get the data from X and Facebook and Google?
