You may as will just show http://images.google.com and complain that it's scraping. Or http://news.google.com.
In general, do you think Wikipedia gets more traffic because Google exists, or do you think Google gets more traffic because Wikipedia exists? Meaning, which affect is larger? I'm pretty sure the answer to this is obvious.
And if more scrapers donated millions to the site they scrape from, the world would be a much better place.
