Sometimes it just shows that something got viral where others didn't.

You could have 200 things mentioning a country or situation, and only 1 or 2 going viral and getting some kind of major response.

It's not like South Park is the only show making fun of China either -- so of 100s of shows and comedy sketches, etc, it was some part that touched a nerve or accidentally got more popular there...

I'd say it also shows that during the period of intensified political pressure, things are more likely to go viral and trigger a strong reaction.
