What I mean by "everyone says that" is that I often read that big tech should be regulated but I don't know what specific end they are trying to achieve.

Tech (big and small) is regulated today and there are rules on the books which protect at least some of the individual privacy points you highlighted. [1] You, and many others, have stated that you find those rules insufficient and would like new/different rules in place.

Can you provide specific goals that address the issues that you think exist, and that law makers could use to draft new policy?
