The data is publicly available. The reasons this should not be an issue are self evident.
Google scrapes trillions of sites every second of every day. Where's the outrage in that sir? Or the legalities. Oh right the law doesn't apply to them. Just small indie devs.
I don't hide behind legal speak and lawyers. I stand behind the truth of the matter. I'd say any legal argument against non-malicious scraping is dead wrong on moral and ethical grounds. Lawyers and powerful corporations will always try to stamp out the little guy to protect their precious trademark or data because their intellects are too dull and mediocre to compete with new entrants or innovations, so they call and cry about it to their lawyer instead. It's easier.
