The example in the video even has the name `authorizer` in the default export, but really it's an `authenticator` or `identifyer` or `isThisUserWhoTheySayTheyArer` – not a `shouldTheyHaveAccessizer`.
I'm in total agreement with you but I guess the AuthN/AuthZ train left the station ages ago and no one outside of the business of selling these tools actually care. Oh well.. :o)
