Should it be the other way around, namely do we have proof that the Chinese government interfered? I do acknowledge that it's hard to know for sure that something does not exist. It's just that there's plenty of news on how Chinese government play favors for its auto industry, for Baidu, and for media companies. But somehow I didn't see any report or even anecdote on retailing, and certainly not for Did (some cities tried to regulate both Uber and Didi).
