Tbh I wouldnt believe a single thing that comes from NASA but that's probably more for the conspiracy threadI find that hard to believe, NASA published satellite images of China showing dramatically improved air quality due to the lack of human activity because of Coronavirus.

With regards to technology tracking everyone wherever they go, that has very serious implications legally in respect of civil liberties. China's record on civil liberties and human rights is atrocious and I have no wish for the UK to emulate them.
