The open letter to President Biden raises serious concerns about the European Union’s designation of five U.S. companies as “gatekeepers” under the Digital Markets Act (DMA). The letter emphasizes potential threats to American competitiveness, security interests, and the estimated $97 billion cost to U.S. businesses. Criticizing the EU’s disproportionate targeting of American companies, the letter calls for fair treatment, an investigation into potential damages, and commitments from European leaders to cease discriminatory measures. Despite commendation for diplomatic efforts, the letter expresses disappointment in the perceived lack of a strong coordinated U.S. government response. The signatories stand ready to collaborate with the Biden administration to address these pressing concerns.
