There is no conflict of interest because it is clear that Uber's goal is to maximise profit for its shareholders - and that is fine. We let Toyota and Starbucks manage the 'algorithm' for pricing cars and coffee, so why not let Uber do the same for rides? If their price is too high then some other company (eg. Lyft) will offer a lower price and grab the business - seems like a free market to me.
