Uber advertises surge pricing as a strategy to incentivize^H^H^H^H^H^H^H^H encourage drivers to become available in areas with high demand.
But if the study's results reflect reality, the surge pricing does not encourage drivers to go to high-traffic areas, it simply drives demand down until it is aligned with the supply of drivers in the area. Driving demand down also discourages drivers from working the area, and thus some actually leave, lowering supply further.
Is that bad? It depends on how you feel about companies being honest with customers. A more accurate message on the app might be "Demand is through the roof, but there are only enough cars for those who need a ride so much that they are willing pay 1.5x the normal rate. Hurry before there are even fewer cars and the surge price raises to 2x."
Likewise, if you feel companies should be honest with their subcontractors, the message for drivers ought to be "Demand in this area is through the roof, and the lucky few who will get riders before we drive demand down, will earn 2x the normal rate. The rest might not get any riders at all, as riders make other plans or flee the area."
According to the article, they are working on tools to help drivers with the latter proposition, but not the former.
If you consider the price changes "dishonest", how do you feel about every other price change in the market? The problem with arguments against surge pricing is that they almost always become fully-general counterarguments against the very concept of a pricing system.

Wrong: "Apples are 10% off this week."
Right: "Apples are 10% off this week, indicating that suppliers are generally willing to offer lower prices for apples now and in the near future, so they should redirect near-term production away from bringing them to market, and consumers should look for marginal uses that they can substitute apples into, like snacks or pies."
That's pretty much unexpected anywhere else.
