There is a verified story that Uber has given up in China. It was like an arms race with no winners. Chinese government just ruled that Uber or Didi can't operate at a loss to drive others out of business. It took communist government to put Travis in his place. Uber has accepted a piece of Didi and will cease to exist in China. Did had already had an alliance or investment with Lyft: Basically, if you can't beat em join em. This uncontrollable growth Uber was seeing was a gimmick, and would not last. The driver incentives and rider discounts were the last straw. Uber went to the wrong market and country. Uber tossed in the towel in China and has conceded to Didi. Monopoly is the new normal and competition is not able to scale like the big players can. Poor Travis finally messed with a bigger, stronger, Bully.
Chinese scammers began ripping off both Uber and Didi by creating fake driver accounts and fake rides, listing them on Alibaba’s online shopping site Taobao, then collecting the big subsidies offered to drivers. Uber's official user accounts on messaging app WeChat were randomly deleted, and Uber drivers began receiving messages saying that Uber service had been terminated in China. These problems seemed to plague Uber more often than Didi — and coincidentally, both Alibaba and Tencent, which owns WeChat, are investors in Didi.
