Still a surprisingly amateur move. Once worked for the Federal Government where literally everything you write is potentially subject to a FOIA request. The message all new hires were told was, very clearly: "Never put anything into writing you wouldn't be happy to be see published on the front page of the Washington Post"
Anything that was even vaguely close to failing this test was handled exclusively by a private phone call or, preferably, in person conversation.
And this was for an org that was doing nothing sneaky or underhanded in the slightest. Still if something could be misunderstood in a negative way, don't put it in text.
I'm still surprised when I see coworkers say things in slack, which is clearly able to be monitors by admins, that don't pass this test. Far more surprised when people knowingly engage in criminal activity and keep any kind of unnecessary record.
