Theory Briefing
- The UK Competition Appeal Tribunal allowed a consumer action against Apple iCloud to move forward, a rare green light for platform lock-in claims.
- The case tests whether Apple's tight ecosystem integration — tying iCloud storage to Apple devices — constitutes illegal market dominance.
- If successful, the suit could force courts to treat switching costs and ecosystem lock-in as standalone antitrust injuries, not just side effects.
- The outcome could set a precedent reshaping how UK regulators and courts evaluate big-tech platform power beyond just pricing harm.
