Or even just print it out. Or put it in a binder. Or make it your desktop wallpaper. Or print it on your toilet paper rolls. Or make paper airplanes out of it. Hmmm it seems like this is a bit of a ridiculous argument. I highly doubt any free government would/could make it illegal for me to print the laws on toilet paper, downloaded via their API.

An app that parses a news sites articles, removes all advertisements from it, and adds its own might very well be illegal in some jurisdictions.

that would be a bit less clear I think .... perhaps it may make it more concrete to think about an example.

Say the education department has a requirement that where ever a student's grades are displayed, the legend to explain their meaning and a disclaimer about limitations is included. It could even be a hard requirement (like, they got sued once for not doing it so their lawyers have told them they must enforce this). So they are careful that in their app, that requirement is always satisfied, since failing to do that could lead to harmful confusion that could impact a student.

So in their view the "document" they made public is the fully rendered version of that. If you print it out you are effectively doing a transformation that preserves its form and essential characteristics. If you screen shot it, cut out the disclaimers and legend and then paste it on a public web site ... you could create the same problems that you are by taking raw data out of the API.
