I agree with most of your comment, but there are a couple of points where I wanted to add some commentary.

Compilation copyright only applies to compilations where some creativity is employed in selecting the items to be included. There is no "sweat of the brow" database right under US law. JSTOR almost certainly does not have a compilation copyright on their collection, since any creativity being employed in selection is being employed by the journals they archive, not JSTOR employees.

At any rate, the indictment does not include any charges of copyright infringement.
