Blizzard has imposed harsh sanctions against a professional Hearthstone player after he expressed support for Hong Kong protesters in their ongoing fight for liberation from the Chinese government. During a live interview over the weekend, Ng Wai Chung (who plays as Blitzchung) concluded by removing his protester-style goggles and facemask and exclaiming "Liberate Hong Kong, Revolution of our age!"
For his actions, Blizzard has levied a one-year ban that prohibits Blitzchung from competing in Hearthstone esports tournaments. Blizzard has also removed Blitzchung from the Hearthstone Grandmasters circuit and stripped him of all earnings from Grandmasters Season 2. Additionally, the two casters who conducted the interview have both had their contracts terminated.
To justify its ruling, Blizzard is falling back on Grandmasters competition rules which state "Engaging in any act that, in Blizzard's sole discretion, brings you into public disrepute, offends a portion or group of the public, or otherwise damages Blizzard image will result in removal from Grandmasters and reduction of the player's prize total to $0 USD, in addition to other remedies which may be provided for under the Handbook and Blizzard's Website Terms."
Of course, Blizzard isn't actually concerned about following the letter of the law to a tee. Blizzard is worried about its good standing with the Chinese government. China is an unfathomably lucrative market from a business perspective. If the Chinese government outlaws anything related to Hearthstone -- essentially scrubbing it from existence throughout the entire country -- Blizzard stands to lose untold profits.
