MMM is broken! How can last year's data possibly be helpful to predict changes in behavior and adjust course during a pandemic? MTA is dead! You can't do user-level measurement without third-party cookies or mobile ad IDs. It’s time to get past all these misconceptions—absolutists always fail to see the big picture.
