If you spent $2500 on Bird subscriptions and rides then that means that the business model is successful at least in your case.
Your comments directly prove the previous poster's thesis.
EDIT:
And yes, Bird has realized the failure in their previous business model of renting scooters, and will be SELLING scooters directly (which in my opinion is a much better business model)
Alas, "Delivering in US and Europe summer 2019" means that they have lost out on $2500 worth of business from goobynight (and from the market segment represented by goobynight).
