Antitrust strategy for the Internet era: a "copy-and-split" of the target into 2 companies:
1) these companies jointly own and can freely use all of the data accumulated and all of the tech developed to date (but as they jointly own it, they cannot sell/license it without the other's permission)
2) each company must choose a new name and cannot operate under the existing name
3) a few months of transitions are granted for each company to decide what their strategy will be
4) all physical assets get split evenly
5) each company get to pick 1 employee turn by turn until each has half of the workforce
And may they live a long, customer friendly life.
