China has sovereignity over Hong Kong.
Blizzard has business interests in China.
End of story.
The demonstrators are now asking for nothing less than changing government form or outright independence.
Neither is going to happen.
Bargaining for something impossible to force attaining something possible sometimes works. I don't think it will in this case.
Young people can see the thrill, but don't understand the consequences. Not just of what they are doing, but what they are asking for.
Communism, democracy, capitalism, state-owned industries, sources of sovereignity - these things are not as simple as people want them to be and sure as hell come each with their own package of good things and bad things.
It's not that I'm advocating "doing nothing", just saying that what they are doing is just really, really stupid.
I understand the need for using your personal fame/exposure to promote a cause you believe in.
But just like actors don't go and insert their political opinions into movie interviews or directly into scripts (they use their own media channels for that), the same rules apply to gamers as well.
In short, a dumb move, followed by a swift reprisal, which was expected.
Blizzard was actually really lenient, beacuse this is a direct attack on their interests.
People involved are lucky in that gamers are not taken too seriously.
