Freedom of speech includes the right to publish and report on scientific results, even when one does not agree with them. It also includes the right to discuss, in an open society, controversial subjects such as climate change, environmental hazards (such as leaking pipelines or contaminated municipal water systems), nuclear waste, and many other "too hot to handle" subjects.
Putting a lid on science is like going back to the dark ages when people thought the earth was flat.
If this repressive regime thinks they're going to get away with this idiotic move, they are sadly mistaken!
