Western media is diverse because they are not all controlled by the same government. For example, the China Daily US Edition is based in the NYC and therefore can be considered "Western media", but being owned by the CCP it obviously publishes pro-PRC propaganda.

Obviously if you define "Western media" as newspapers providing a certain viewpoint then by definition your argument would be correct. But that isn't an interesting argument.

Moreover, using the Internet people in the US can read diverse points of view, including e.g. those of pro-China websites. This is not possible in China, except for a small minority who have access to VPN and similar technology.
