The recent American criticism was caused by US congress

hearing where US companies in China, under presure from CCP, implemented intenet filters to block political sensitive information. The worst case of Yahoo, HK is that Yahoo, HK gave out chinese dissent private informtion and resulted in him being arrested.

These are well established facts.

To arrest and sentence people for their internet posting for more than 10 years is unprecedented worldwide.

For all other trivil and inconsequential things, chinese can freely talk. That is some of freedom of speech. It is way not enough.

It is well known to the world that China does not allow dissent voice anywhere.

CCP strictly controls what should be in news; what should be tolerated; what is never tolerated at all. Even for those freedom mentioned in your article, CCP has final discretion on it. You feel like you have freedom of speech. It is because CCP give it you. They can take it back, though.

Without you knowing, they actually had made a deal with you : if you do not go against me, I let you sing like a soundbird.
