I'm not claiming it's sufficient. Perhaps it's not. But it seems mistaken to use anti-trust regulations to break up or regulate companies when there are still laws on the books that help facilitate market dominance. Repeal those first and see what happens before doing anything else. Any legal rule that makes legitimate HTTP requests illegal (i.e. requests whose purpose is not solely to commit harm ala a DDoS) ought to be repealed.
