Apple is facing a £3 billion ($3.8 billion) lawsuit in the UK from consumer group Which?, alleging that the tech giant breached competition law by effectively locking around 40 million customers into its iCloud service. Which? claims Apple has abused its market dominance by encouraging users to sign up for iCloud while making it difficult to use alternative cloud storage providers, resulting in overinflated prices. The lawsuit argues that Apple's practices have stifled competition and led to consumers being overcharged, with estimates suggesting affected customers could be eligible for approximately £70 in compensation each. Apple has denied the allegations, stating that iCloud use is optional and many customers utilize third-party services. The case is being filed with the Competition Appeal Tribunal, and if successful, it could have significant financial implications for Apple. This lawsuit is part of broader scrutiny and legal challenges facing tech companies for alleged monopolistic behavior.
