Apple was not able to narrow the scope of a UK lawsuit accusing it of locking 40 million UK consumers into iCloud, to the detriment of third-party cloud storage providers. British consumer group Which? first filed the lawsuit in late 2024, and is asking for £3 billion for UK Apple customers. Apple wanted to exclude non-paying iCloud users from the lawsuit, but the tribunal denied Apple's request in a 2 to 1 majority.
To your point it’s one of the levers regulators and governments have against corporate entities.
It’s a difficult venue, but it does work even if it seems like it has a minor effect. It creates disincentives and incentives which business are influenced by.
It would be better if regulators had more teeth, but capitalist defang whenever they can. Be it laws, regulators, or even just public influence.
