This has the makings of a classic David v. Goliath story. In April 2025, soon after Trump's 'Liberation Day' drama, a few little-known US companies gathered the courage to take on the president. Ten months later, they succeeded in dismantling his signature tariff regime. The timing could hardly have been more striking. When the lawsuit was filed last year, Trump loomed large on the national and international stage. CEOs of major tech companies, bank executives and corporate leaders appeared eager to remain in his good graces, offering gifts and making large commitments, while remaining reticent in offering opinions on Trump's policies.
