Big Tech howled over E.U. antitrust law. The White House declined a rescue.

As European Union regulators prepared to implement a Big Tech law that would broadside U.S. heavyweights such as Apple and Google, the letters poured into the White House.

A group of industry associations wailed to President Biden that Europe had used “subterfuge” to “hobble U.S. companies.” A band of members of Congress bemoaned the E.U. law as “de facto discrimination against U.S. firms and workers” and warned that it would give a leg up to China and Russia.
