The problem with this is that reading the generated HTML behind a page that has been served to your browser does not prove that data was stored in an HTML source file. The data is inserted into the page while it’s being served to the browser. That’s what the JavaScript does after it requests the data from the backend code, which gets the data from the database (or whatever storage is being used) and sends it back to the JavaScript, which puts it in the page.
Saving data in source HTML files would mean every possible combination of data anyone might request must be saved in its own separate file, which is definitely not how web development is done. Laws should not be made by people who don’t know what they’re talking about.
