You think that DO sent out a shill to pretend to be a throwaway to give hackernews confidence in the DO platform?
My read of this is very different than yours: Naive IC who doesn't have optics into the actual mechanization of the business trusting the CTO fully.
I think this message from the CTO is a partial truth as they often are in orgs that aren't extremely internally transparent.
AKA I don't think the "shilling" is working if that's what they were doing.
