>Adding up the big "ad-based" companies (google, meta) gets into the double digit percentages of US GDP (and those companies also do some useful non-ad things, too). this comparison is meaningless because you're comparing market cap (stock) with GDP (flow). If you only compare revenue and GDP you get a far more modest 1.7%, and even that's misleading because you're comparing global advertising revenue with the production of one country.
