It is an odd decision for a site emphasizing the ease of onboarding visitors. Also unclear to me also what that particular snippet does? The marketing seems to imply you can skip some or all of the classic new account/login page via 'magic', so why isn't that being demonstrated here?
Similar on the need for a phone call (what is this, a pizza?)--at least let me hide behind email. But then I'm probably not the target customer, so do as you will.
