I don't think you should frame your stance as "you buying the game = entertainment > human rights" because it's a bad faith argument.
I agree with not supporting Blizzard, but dying on that hill means you also die on the hill that you believe your work / social life / etc is more important than human rights because you own a cell phone and a computer made in China. It's just bad faith.
Well, my phone is from one of the few brands who don't manufacture in China anymore, but sure. That's not the point.
The point is that if someone says "yes, Blizzard is wrong to support China, but I'm gonna buy their products anyway because [insert some made up argument about how the poor devs who are indentured workers at said company deserve their salary they were gonna get anyway] or because I just
need my games", then it's fair to say they care about their entertainment more than they care about the cause in question.
Again, that's fair. It's up to everyone to decide what is important to them. But they should be able to admit it openly and not hide behind some made up bullshit.
