My point is that post "Free Hong Kong" all you want, whatever that means. ("Five key demands, no one less." is more appropriate) Saying Blizzard is somehow supporting genocide because they banned blitzchung is hyperbolic. By the same logic, all AAA video game companies are in some way supporting some atrocity.
There is active complicity and passive complicity. Reprimanding Blitzchung in a clear show of force and appeasement is active complicity. Saying that Blizzard supports genocide
is hyperbole, but what we know for certain—not only with their Hearthstone action, but with prior actions like referring to the Taiwanese Overwatch team as "Chinese Taipei"—is that Blizzard applies their own internal policies, within their own power and jurisdiction, to concord with China's national interest. It's fair play to emphasize that this particular national interest, writ broadly, is not okay.
When people bring up the ethnic cleansing in Xinjiang, that is shorthand for saying: remember which country we're dealing with here, and which country businesses are tripping over themselves to enable.
