If they did use whois data, then what would stop anyone harming a competitor by registering a few sites with identical data of a competitor and then developing some poor quality sites, thus damaging the competitor site?
I was always under the impression that no outsider could directly harm your site with links from poor quality sites, so if Google did use whois data, then technically a site could be harmed from outside interference!
