Hearthstone caster and well known TCG personality Brian Kibler announced his departure from the Hearthstone Grand Master in protest of Blizzard's harsh treatment on Hong Kong player BlitzChung.

“I won’t pretend to understand either the intricacies of the geopolitical situation in China and Hong Kong or the full extent of Blizzard’s business interests there,” he wrote. “But to me this penalty feels like it is deeply rooted in both. The heavy-handedness of it feels like someone insisted that Blizzard make an example of Blitzchung, not only to discourage others from similar acts in the future but also to appease those upset by the outburst itself.”
