Anti-monopoly laws are good, but how about some harsh anti-duopoly laws? Could also hit the iOS-Android bird with the same stone!
There's no escaping the politics here. You can't enforce antitrust without hitting the billionaire class directly, and those people know how to influence American politics in their favor. Just look at what happened to the "click to cancel" rule post-Trump, something that is unambiguously pro-consumer and exactly the type of thing the FTC should be doing.
