US Senator wants to ban all future acquisitions by Big Tech Facebook WhatsApp In line with growing calls for antitrust regulation in the US, Republican Senator Josh Hawley has introduced legislation calling for the ban of all mergers and acquisitions by companies with a market cap of over $100 billion, presumably targeting Big Tech companies Microsoft, Google, Apple, Amazon and Facebook. Called the “Trust-Busting for the Twenty-First Century Act”, Hawley’s bill proposes overhauling century-old anti-trust and competition laws such as the Sherman Act and the Clayton Act. Hawley wants to clearly define the anti-competitive behaviour under the Federal Trade Commission (FTC) instead of getting bogged down by lawyers and economists.
