Yup. The price jump isn't just a "surge." It's the algorithm calculating the highest price you'll tolerate without abandoning the app long-term, no matter availability of cars (which can be related, but from CFOs perspective that's not the metric to optimize)
This personalized price discrimination is precisely the kind of manipulation geohot is describing.
It's the same principle as (an old story) booking.com charging Mac/Safari/iphone users more.
