There are some interesting articles being written about the Beijing 2022 Olympic and Paralympic Winter games and the privacy of those who will be attending. The basic message seems to be take a burner phone with you.
The issue is around the amount of personal data QI-ANXIN (an official sponsor of the games) collects when users connect to their services. Of course one thing to remember when using any connected in China is that your privacy may be compromised, compared to what happens when you are connected at home!
Here are a variety of articles around the issue, so you can make your own mind up.
