Right. From the Ars article it seemed that it was Google employees looping in Google lawyers while communicating with each other, not Google employees looping in the lawyers while also talking with third parties. So more like if I and a colleague both go to legal to hold a conversation just to gain the benefit of their presence to call it privileged. But if the lawyer is just sitting there working through a book of sudoku puzzles, then it's probably not really a valid claim of privilege.
From the Ars article:
> In 2016, Google instructed employees to create artificial indicia of privilege for all written communications related to revenue-share agreements and Mobile Application Distribution Agreements (MADAs), the exclusionary agreements at the heart of this action. Google reiterated those instructions after the Department of Justice issued its first Civil Investigative Demand in the investigation preceding this case. The Court should, therefore, sanction Google for its deliberate and deceptive misuse of the attorney-client privilege and order the company to produce, unredacted, all emails between non-attorneys where included in-house counsel did not bother to reply, indicating that any request for legal advice was most likely a pretext.
