"The advertising of "infection rate is slowing" is a lie because a) the total number of infections is not able to be observed and b) the screenshot chat shows a 300 per day infection rate which is not slowing, the acceleration rate (increasing daily infection numbers) is slowing."
But the point is one can't know if the statement "infection rate is slowing" is true or false.
Ergo, how can one definitively describe it as false, as you have done?
