If you read any EU directive (like the DMA) it'll start with a bunch of recitals that explain the intent and background of the law. Sometimes these are longer than the actual articles.

As far as I, as a layman understand, the legal practice is that these recitals can not contradict the main text but that they are intensively used by courts and to politicians to resolve open questions where the formal law is appropriately unspecific.

So yeah you can read the intent of the law.

As well, I don't think we can say Apple thinks they're complying with the law. That would be protected under attorney client privilege. They only weigh up the risks of penalties.
