A U.S. federal judge dismissed a proposed class action lawsuit filed by Amazon Prime Video subscribers challenging the company's decision to introduce commercials on its streaming service. The lawsuit argued that Amazon breached its promise of ad-free streaming by adding commercials without user consent, except for those who paid a $2.99 monthly fee to opt out. The court ruled that the introduction of ads constituted a permitted "benefit modification" under Amazon's terms of service, rejecting claims of breach of contract and consumer law violations. The ruling allows Amazon to continue showing commercials on Prime Video unless subscribers pay the additional monthly fee.
