I have an idea for reducing surveillance capitalism:
Every time a company sells (or gives away as part of a commercial transaction) any information about you (name, location, unique identifier, website you visited, etc.), they have to mail you a postcard telling you what they sold and who they sold it to.
Bonus: Boosts the post office as well!
@philipbrewer I like the playfulness of your idea! I think I rather would ban them from doing it* though.
*) If at all possible.
