There are many in tech whose jobs rely on selling personal information in ways that users would never consent to if they were made fully aware of what was being collected, how it was being collected, and how it was being used. I can't imagine it feels good to constantly deal with the cognitive dissonance required to participate in such schemes.
But compared to sharing of my private medical information within the government and to external private parties to enable government tax collection ... THAT I object to 100x more, but it never seems to make the news. I would like to see a blanket ban on government departments sharing ANY data beyond "this person exists", with exceptions approved on a case by case basis by congress plus heavy fines for government departments found in violating of these rules. Maybe even personal criminal liability for government employees actually doing the sharing if that's necessary to stop it.
