It very much is Apple's problem, because Apple made it their problem. First off, the EU is only asking about Apple's own App Store and how it prevents scams in there. It's not asking about iOS as a platform.
However; Apple explicitly went out of its way to be malicious in how it implemented the DMA by requiring apps that want to publish in third party app stores to still be validated by them and pay for that too. If the EU wants them to answer for how scams get through that process, that is fair game too. Microsoft and Google don't do this, so it won't be a problem for them. Apple decided to create a malicious system to discourage users, and if the EU now comes knocking on their door for it, well... Karma.
Regardless, there were - and still are - plenty of apps in the App Store today that scam users into ridiculous weekly subscriptions, etc. So let's not pretend Apple is doing a very good job even in its own app store either.
It's sad to see that instead this article is clearly just jumping on Apple's bandwagon and maliciously portraying the situation and what is being asked of them, just even the title alone, and sadly the comments don't seem to be any better.
