A series of embarrassing emails have come out, following embarrassing text messages which were revealed in the fall. Some perspective is needed here, though.
Companies are frequently undone by emails. DNC emails certainly didn’t help Hillary Clinton during the 2016 Presidential election. Emails hurt Microsoft when the government prosecuted an anti-trust case against it for monopolizing the web browser market (gosh if everyone knew then what we know now). It amazes me that companies store past non-work related emails.
