To be fair, unless the execs are also forgoing salary or bonuses, like Nintendo execs a few years ago for example, you can't really win with these layoff emails.
If the emails are succinctly composed then people would complain that the announcements were too curt and don't try to assuage people enough.
Shocker that management taking away the livelihood of tens of thousands of individuals due to management failures can not be reduced to a positive email.
even this one hints to this "people wanted more visibility and notice". You'll never make everyone happy, so it's a mistake to seek the "perfect communique"
