Speech in the US is powerful enough to cause consequences, not really sure what you're talking about.
The US just changed administrations & congressional leadership twice in 4 years based on nothing more than ballot speech, which involved the humiliating defeat of one of the most well funded "establishment" politicians in favor of a non-politician that made a mockery of establishment practices for 4 years. Congress has representatives reviled by practically all of their colleagues and party management, yet they consistently get re-elected through ballot speech.
A series of news reports took down an entire presidency and the whole government couldn't do anything about it.
Allegations of sexual misconduct alone have sunk the careers of some of the most respected and powerful figures in multiple industries.
Protests & news reporting have directly led to historic civil rights legislation, and more recently: local council votes on police spending measures.
Sure, US politicians can be eager to censor but there are political & legal mechanisms that restrict and stop them. There is no such thing for the CCP. I've yet to see any checks on its power or speech about the CCP's atrocities & coverups affect the CCP's permanent leadership.
