I think Dorsey's email is pretty crap-free. I think to the extent that he employs long forms or euphemisms, it's intentionally intended to communicate compassion.
Management is hard, because people are going to read any interpretation that they want into your actions, and there's almost always the potential of reading in a negative interpretation. You truly can't please everyone. All you can do is try to do the best, most reasonable thing, and keep as many people on your side as possible while doing it. There's probably a lot more people that would see "we're cutting" as crass than there are people that see "we're reorganizing" as patronizing.
There would be no reason to make disclaimers otherwise.
It's a form of the, "I'm not a racist, but...", style of argument.
The fairness is in the labeling (we do not want to unfairly label those who were not actually dishonest or unprofessional; sometimes mistakes do occur), not in the response to the behavior.
But for the most part it does lead with the decision being communicated, i.e. that there will be a "restructuring of our workforce", commonly understood to mean layoffs.
