I’m always keen to shit on Google, but, this is about “having search terms in the query string” and “having links that take you directly to the thing you clicked on without any redirect dance to obfuscate the Referer header”. With all the other shit to legitimately complain about from Google, this seems so silly to focus on. Google isn’t even the one that sent the Referer header, that would be your browser (which, Chrome didn’t exist yet at the time). RFC1945, from 1996, for HTTP 1.0, even explicitly stated that any application that communicates over HTTP (i.e. a web browser) should offer the user a configuration option to disable sending Referer headers.
