With nowhere near the same implications.
> The US government is no stranger to this, where COINTELPRO [1] used the results of domestic spying to try to put an early end to MLK and the Civil Rights Movement.
The big difference being that COINTELPRO was not done with the authorization of Congress and instead lead to a Congressional investigation and later the Senate Intelligence Committee to provide oversight [1]. The airing of those abuses culminated in additional oversight of domestic intelligence activities.
In China, the airing of those abuses would end with the journalists being censored/bagged.

A National Security Letter is hardly an absolute order. They can be reviewed by a judge. They cannot include requests for content like messages. Those require a warrant. They can be beaten in court. They are not a broad tool that the NSA can apply as they wish for whatever ends they wish. Not only that, citizens are allowed to oppose it and elect legislators to repeal them.

The lack of prisons full of political dissidents who committed thought crimes on the internet puts them head and shoulders above. The existence of an independent judiciary does as well.
