I couldn't read the article because of paywall. But from the part you quoted. It seems like this can be a plausibly scenario: - Someone (possibly a group of people) is trying to organize a time for maximum attendance for some meeting or protest. - They are checking peoples "public for internal" calendars, maybe sharing between themselves. - "Screenshots of some of their calendars, including their names and details, __subsequently__ made their way outside the company." This means they are not leaking the screenshots to outside from my understanding. As google has access to all data, reason why this calendar screenshots shared etc, and never mentioned here, making me suspect google is at fault here.
