This is the absolute root of what's going on, right here. Twitter is only nominally a tech company; it's a media company. It may be that he had to cut the fat over there, I don't take issue with that necessarily (though I certainly do take issue with the disrespectful way he went about it), but image is incredibly important at a media company and he's notoriously bad at comms except with a small subset of people. Twitter needs sensible policy and thoughtful communication, and he wants to ram his ideology through it like he would shake up any technical process.
