I might be missing something here because nobody else brought it up: Is this not just a necessary move to salvage investments in Lyft? Assuming Uber won already, Lyft investors need to keep it dangerous enough to force a buy out or write it off completely. Keep Lyft alive until Uber is forced to buy it pre/post IPO? At some point the Lyft competition is going to cost Uber more than the price of just buying them out. Please note that I am not a biz guy so if I am wrong I would be very happy for an explanation on how/why.
