I really don't like Dan Ambramov's style of communication. It's terse, impersonal and authoritative in a way that implies an attitude of "I'm right, you're wrong, stop wasting my time and go away". In my decade plus of experience in the software industry this has been a reliable indicator of the type of people I don't enjoy collaborating with.
