They do not have a sustainable business. They're clearly pumping up revenue with subsidies (which is why they lose so much money). I do use Uber occasionally but when I do there's so many offers and deals that I never pay anything close to a break-even price. If you sell dollar bills for 85 cents it's easy to have lots of revenue.
