On October 6, 2019, during the Hearthstone Grandmasters streaming event in Taiwan, Ng Wai Chung, a professional Hearthstone player and resident of Hong Kong known as “Blitzchung”, was being interviewed following his match, during which he donned a mask similar to those worn by protesters in the 2019–20 Hong Kong protests and said “Liberate Hong Kong, Revolution of our times”. The stream was cut off shortly after. The following day, on October 7, Blizzard announced that Blitzchung had been banned from the current tournament, would forfeit any prize money (approximately US$4,000 by that point), and would be banned from other Grandmaster tournaments for one year.
