herewego,
I had a look at her posts, you seem to have a very different view in my opinion. She is certainly not standing up to anyone, in fact she states that the company have told here to stay neutral. She has declined media interviews from Al Jazeera and bloomberg etc, hardly standing up to the HK government and CX. If she was, I would expect to see her giving her real thoughts and opinions.
I am certainly not a fan of these insta heros, far too narcissistic for my liking, but I agree, she could use this platform for a good cause and exposing what's happening here to some of the worlds media and not sitting on the fence.
