Earlier quoted context omitted.
FWIW, there is no visible pressure that has been exhibited from China against Blizzard. There have been no statements from China either in support or condemnation of any of the involved actors. The situation is entirely driven by Blizzard, for fear of their potential revenue stream out of China. This is in contrast to the NBA scenario, where China did speak out against the NBA, and later began to cancel contracts.
You can't say there is no visible pressure on Blizzard while mentioning the NBA in the same breath. China's aggressive move on the NBA is the pressure. It's an example to every company that operates in China: toe the party line, or face local obstruction like the NBA.
That they chose to toe the party line on their own, without prompting from the Chinese government, with swift and overwhelming penalties on the player and shoutcasters doesn't exactly speak well for Blizzard.
