This creates an interesting little micro-paradox. Customers in the US claiming they will boycott Blizzard over this situation are precisely why Blizzard is motivated to act in this fashion. Because there would be a mirror situation in China with a vastly larger customer base acting in an equal but opposite fashion. Until people (around the world) can accept individuals behaving in a way they find deplorable, we're only going to end up in a world where the biggest wins. And as the geopolitical status quo changes, that's no longer simply synonymous with USA or even the west in general.
This is one of the many reasons I think the trend of 'free speech is only the government' is so incredibly myopic. People don't consider that the views they support will inevitably also come under fire from the powers that be - and they'll rapidly find themselves facing silencing and censorship with no recourse. Free speech is a value, not an amendment. Dismissing this because it's convenient is something that will only come back to haunt people as the tides shift, which they inevitably do. We should base our values on a system of ethos, not whichever chain of often contradictory positions we think will work as a means to achieve whatever ends we think we're going to get.
