If you believe this you either haven't read all of my posts or you cannot understand them.
The only difference between the search engines (of which there are a lot more than just the big three) and other scraper sites is the scraper sites are a lot more discriminating about the sites they choose to scrape (most notably Google).
Yahoo, Google, Alta Vista et al have rightly earned their legitimacy by being first, being massive, and receiving (and sending) tons of traffic, but trying to claim they are any less of a scraper site than the "scrapers" described on WebmasterWorld is simply out of sync with reality.
Do I hate scrapers in general? Yes. With a passion. Do I hate all scrapers? No. I happen to love Google, Yahoo and MSN, for purely selfish reasons. If you're honest with yourself and others you'll admit to feeling the same way. We're all motivated by "what's in it for me?". That's what makes a capitalist system work so well.
