Following Apple Ireland getting fined for paying out to Russian app developers, the company has ceased all payment processing for the country, meaning users are cut off from buying new apps, or continuing to subscribe to Apple Music.
Arguably, if a user in Russia subscribes to a Russian developer’s app, that’s between them. But since Apple hosts such apps and takes a cut before passing earnings on to the developer, this means Apple is dealing with Russian businesses.
There’s a sufficiently grey area here that Apple Ireland — which is responsible for all non-US Apple business — told regulators about it. And those regulators decided “on the balance of probability” that Apple had broken sanctions.
