In October 2019, American video game developer Blizzard Entertainment punished Ng Wai Chung (吳偉聰) (known as Blitzchung), a Hong Kong esports player of the online video game Hearthstone, for voicing his support of the 2019–2020 Hong Kong protests during an official streaming event. The public's response, which included a boycott and a letter from United States Congress representatives to Activision Blizzard, prompted Blizzard to reduce the punishment, but not to eliminate it.
