> suddenly 95% of new cars purchased were Fords, we probably shouldn't initiate trust-busting action against Ford on that basis alone.
Antitrust law isn't about stopping people from accumulating a dominant position. It's about stopping people from using that dominant position to maintain itself or to spread to other areas. Ford produces the "Amazing Car" that everyone wants, costs $1, etc. great! When Ford uses an RFID reader to force it to only fill up at Ford Gas Stations antitrust steps in. The issue isn't that Google is the dominant search engine, but that it uses that to become dominant in ads. It's not that YouTube is dominant in video, but that uses that to encourage people to download Chrome.
Good take, very much agree. That’s why so many of the antitrust work against Google/FB, etc. has focused on acquisitions. They become successful, then use their data and infinite money printers to buy anyone who would compete.
