Yeah you guys have to pay attention to the state of the overall economy. We are in the credit-crunch phase of a recession. The funny money has ran out and infinite loans are no longer available. These companies have to find way to pay their debt now

Billions of USD in debt, a business model bleeding cash with no profit in perspective, high-competition environnement, a sub-par product, free-to-use offline models taking off, potential regulatory issues, some investor commitments pulling out... tricky.

But let's not cry for the founders, they managed to get away with tons of money. The problem is for the fools holding the bag.
