Want to add to this. Tiktok blatantly violates Google's device ID policy, and actually admits it in writing.

> We share your device ID with measurement companies so that we can link your activity on the Platform with your activity on other websites;

My contact at google said a year ago when I asked if they know about Alibaba's device ID abuse for advertising targeting, it's their policy to not to touch Chinese companies' device ID abuse.
