Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
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. Blizzard also terminated their contract with the two livestream presenters who were interviewing Blitzchung. 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.
