"Attorneys representing a Google employee suing the company want to know whether the search engine giant thinks it is allowed to view his digital communication... [and] access the personal data of non-employees involved in the case, including the judge." https://www.washingtonpost.com/technology/2020/09/22/google-employee-surveillance-lawsuit/
In summary, the company's ToS allow it to access user data to "protect Google" so does that extend to everyone involved in a legal case against Google? Interesting implications for people (and govts) who have brought cases against Google while using Google services.
I bet the client and attorney were coordinating their case over gmail and gdocs and realized Google gave itself the legal right to access that data. I wonder if Google did something in the case that would only be explained by that action?
