What a stupid law suit and what uneducated comments. Imagine thinking Google owes you real money for query string parameters during a time where even ssl was still quite optional on most of the web.
It’s a stupid lawsuit, but it does ensure a precedent that search engines should sanitize the referer when sending you to a link you click on. If some unsuspecting user accidentally types their credit card number into google and clicks on a shady website that says CHECK VISA FRAUD, that website absolutely shouldn’t get the data of what the person typed in while doing the search.
