I think one of the interesting things that will be covered in this lawsuit is whether the licence under which the code is released applies at all in the case of screen scraping. The current understanding of screen scraping is that it is allowed, despite what is in the websites terms. Effectively if a human can access the content freely without having to actively agree to a license or terms you can scrape the content.…
Screen scraping is essentially a question of whether or not the actions constitute something akin to hacking, which is almost completely orthogonal to copyright. The main intersection you get is that many screen scraping scenarios are about things that aren't copyrightable (the US doesn't recognize "sweat of the brow" doctrine, so databases aren't copyrightable). When Google was scraping lyrics off of lyric sites--lyrics being totally and clearly copyrightable--it was dinged pretty hard for that.
