Great point made in this Hacker News comment:
Corporations will abuse your personal integrity whenever they get a chance, while abiding the law. Corporations will cry like babies when their publicly available data (their livelyhood) gets scraped. They will take you to court.
They consider their data to be theirs, even though they published it on the internet. They consider your data (your personal integrity) to be theirs as well, because how can you assume personal integrity when you are surfing the internet?
