A Hearthstone player came out in support of the Hong Kong protests recently during a stream. Blizzard removed him from a competition, suspended him for a 12 years from competitive play, and rescinded his prize money for supposedly violating its official competition rules for the tournament. In my opinion, the rule itself reads more like an exit clause for when players engage in offensive or illegal acts, and it seems questionable as to whether a political statement is (or should be) caught under the rule.
It is noteworthy that Blizzard is partly-owned by a Chinese company and has a huge Chinese following. At the risk of sounding partial, it is disappointing to see one of the biggest video game companies whose mission statement is “Every Voice Matters”, kowtow to an oppressive regime. This is also interesting because right now the NBA and South Park are also embroiled in identical incidents, and both of those entities came off as more democratic and pro-Freedom of Expression, even though the NBA’s stance on this issue has been milquetoast at best.
