It does beg the cascading question too.
What if I create a search product that directs you to a site, based on information gleaned from another site?
Trivial example: a "Top 10 Topics in the News Today" list of Wikipedia links, based on scraping a news site's front page daily
On the one hand, "It's free info and scraping should be allowed." On the other hand, if everyone did that, it'd highjack all of the news site's visitors, depriving it of revenue and destroying the very resource it's built on.
