It isn't PR speak when you just tell the truth in an email and don't let management bully you into not saying what needs to be said to prop up their take on it.
It can end up a bit dangerous, because they'll be more than happy to drag you through the mud in court to try to discredit you, but a lot of people kinda expect that anyway.
No, the whole culture around email changes when people know for certain it’s part of the public record of the company. I’ve worked in environments where all emails are retained due to government contracts, and an unwritten rule immediately emerges that nothing that could be used against the company is said in emails. Backchannels emerge with IMs, SMS, etc where the real conversations happen.
