I think it is extremely useful to look at another parties actions to decipher their intentions when those intentions are opaque. As 956 states below, the Chinese government has banned TT in their own country, but promote it heavily here. What does that tell you? You could dismiss it as a strange coincidence but knowing what we know about the Chinese government and their intentions towards our society I think we can make rational inferences .
And for those saying “what do i care if the Chinese government knows I like seeing cats doing stupid shit” you are incredibly naive if you think that is the data they are mining from your phone. They can mine your interests, everywhere you go, everyone you know, and probably can predict your behavior better than your spouse. And that is before we discuss how the world view and “facts” you are exposed to can be easily manipulated to affect public opinion in this country.
