I have no idea how Tesla operates internally, but I wouldn't be too surprised if, like at most companies, letters that go out under the CEO's name are vetted by both the legal and PR departments, and possibly written or edited by them. If that's the case, then "Elon Musk" is a sort of composite entity, which includes a human named "Elon Musk", but not solely that human.
I would agree. But there's nothing in here that's cause for concern legally. And PR folks are going to have a tough time overruling Elon based on "style" points. As I mentioned he probably sees nothing wrong with his approach and thus any PR comments would fall on deaf ears.
