Written it in another comment. If there are ambiguities in the written law, for example because the legislature did not specify in the text of the law, that you can't charge for the access to the platforms, high courts like the CJEU will take approaches where they determine the spirit of the law (i.e. by looking at the discussion material the legislature presented for passing the law) to find out what the intent of the legislature was and then defines this law.

This is for example how Germany now has a basic right to data protection. It's not written in the constitution, it was formed by our supereme court by looking at what the intentions of the author's of our constitution were. Same principle applies to EU laws.

I agree that this is not a citizen's job. That's why I wrote that I am very happy to see the EU commission drag Apple in front of the CJEU.
