Blizzard, perhaps ironically, has ignited a firestorm over the banning of an esports pro for his support of Hong Kong. While the initial response was flammable enough, the aftermath is swiftly growing beyond its original gaming context into a proper international incident.

If you want the skinny on how this whole thing got started, you can read the details here. Long story short, a Hearthstone player called Blitzchung spoke out in support of the protesters in Hong Kong, his hometown. Blizzard subsequently banned him from competing for a year, stripped him of his winnings in the tourney he was competing in, and broke with the casters who were interviewing him.
