An ad'free world means not seeing info on new start-ups or small businesses who rely heavily on analytics and ad placement.

The data collected does not provide personal identifying info like name, ssn, or id numbers, not address or any of that.

The data is usually "city, interests, age." That way if you like all natural beauty products, small businesses can still reach you.

In what you all consider an ad-free world, there will still be ads. It'll just be the big corporations and a return to the pre-internert domination of big brands over the rest.
