And while AT&T doesn’t seem to have done this, other companies such as Apple have enacted privacy measures which directly contravene the stated wishes of the government - but which are legal.
In China, I believe the way it works is, whatever the government wants becomes legal. The US is far from perfect but the rule of law exists here to some degree.
In China, they want this information public because they want people to know that they know and self regulate - Panopticon.
The cynic in me looks at the US as a country controlled by companies while China is a country that controls companies. I don't know if it makes that much of a difference any more now that companies are almost the same size as countries.
Either way, the current reality of some lucky individuals having all the access to everyone’s information, whether it’s Chinese government or companies or US government or companies is the worst situation to be in if you have little power, i.e. 99.9999999% of people who aren’t billionaires/nation state level diplomats.
