Didn't link to Zitron site but if you can't see how dishonest it is to say you have $19b ARR when the reality is you have only a total of $5b IDK what to tell you. Says more about how you think and why you think it's okay for corporations to be misleading.
Seems natural to me too. ARR is understood as the current rate. It would be more misleading to say 5b ARR.
Its like asking how fast a car is moving.
