The devil is in the details. If the probing test requests are for domains that Google owns or has permission for junk queries, then no one outside Google has standing to complain. The only people affected would be abusers (NXDOMAIN hijackers), Google, Google's users, and Google's users' agents (ISPs). On the other hand, if Google is deploying something that does random queries of third party DNS servers, then Google is being almost as evil as the "sender verification" spammers who sent unsolicited bulk email (spam) to the every apparent source of incoming mail, including obviously forged spam. Every entity that outsources its abuse detection without the informed consent of the outside providers of labor and other resources is an evil abuser, regardless of the abuse being detected, the real or claimed intentions of the outsourcer, and its other good deeeds. Is whatever Google doing documented somewhere? I didn't see anything with https://www.google.com/search?q=chromium+nxdomain+detection+dns and one or two similar searches.
