And thanks to Snowden revelations we know for a fact that US companies work directly with US government and share all their user data.

Sure, but there's a difference between having the potential to do something, and actively doing it. I'm aware the FBI/CIA can get my data from Google if they want it, but something would have to trigger them into wanting to investigate me. With a Chinese company there is no "if", all of the data goes straight to the CCP. Tencent, the bloated multimedia company, even had a moment of ironic hypocrisy where they didn't want to give away all of their users' data.
