Indeed. It would be interesting instead of some of the Lina Khan style "cleave a company apart" trust busting we instead had a push for government action to enforce this state of affairs, given the nature of the private incentives.

This would also be more transparently a benefit to consumers, as I recall one of the hurdles in the present state of anti monopoly law is present monopolies (like notably Amazon) have rather obviously reduced costs/made life easier for consumers.

This tension between these companies and consumers becomes more obvious as companies resist these moves while more and more consumers adopt LLM intermediaries.
