I disagree that it's reductive. If each user costs more in API tokens then your company isn't valuable. That's what everyone's been screaming from the rooftops about there being a bubble. We certainly use tons of AI at the company I work for, if we were paying full API prices then I would bet we'd be barely using it.

I have the impression that if MAU by itself was sufficient, the company wouldn’t have had to file for bankruptcy.

Obviously the company failed to convert its MAU into paying users, despite the fact the token costs greatly declined over the last years.
