Earlier quoted context omitted.
This is not even contestable. Google and FB took the advertising money from everyone else. Businesses still pay (and always have) the same % in advertising, only it's 2 monopolies now instead of thousands of media.
I'm no fan of ads, but I would still contest that. The pre-Internet advertising arsenal was all remarkably blunt weapons (newspaper ads, TV, radio, direct mail) that made targeting very difficult and were out of reach or not economic for countless businesses. Now anybody can buy precisely targeted impressions for any keyword under the sun and very closely track their performance, opening up entirely new markets.
Before deciding if "opening up new markets" is necessarily good we'd need to ask what kinds of markets it opened up. Most of what I see are content farms flooding search engines with SEO garbage, scammy businesses that sell poor knock-off products, and predatory ad tech. I'd prefer it if those markets had never been opened.
