It's 2022. Who doesn't know that email/text messaging isn't private??

tl;dr: NY Times article says [the University of Michigan president just lost his job](https://www.nytimes.com/2022/01/16/us/mark-schlissel-fired.html) for an "inappropriate relationship" documented via email. [Link to the emails](https://regents.umich.edu/files/meetings/01-01/Communications.pdf)

The emails they posted aren't really super-incriminating...but the point remains, who is still thinking that electronic communications are private? I guess if you're an executive you can usually get away with this sort of stuff because you own the place and can sweep it under the rug...but when you're in a public job you're one angry person away from an email leak.

I've never been an email admin, but I assume it's pretty routine for lawyers to go fishing in executives' email whenever there's a lawsuit. Do executives know their secrets could be exposed or do they just not care or think anyone will do anything to them?
