Well, my point isn't really about whether I care or not. Any rational actor wouldn't give any weightage to celebrities supporting an authoritarian regime, simply because they don't have any other options. (The "option" to keep quiet can be taken away any time. Although I agree that this particular instance wouldn't warrant such measures.)
I find it interesting that you say that at any time they could be forced to say something. Can you show me some sources that indicate that this practice exists after the end of the Cultural Revolution? I am not criticizing you, I truly want to know because this is not something I am aware of.
Can you comment on past track record? In any of the previous boycotts (for example against Dolce & Gabanna who made a racist video, or against Japan honoring war criminals), have you seen evidence of peopke coerced by the government to say something, or people being prosecuted for staying quiet?
Again, my point is that, if an authoritarian government has the power to silence a person, then they certainly have the power to make a person say what it wants them to say. (Not directly related, but "confessions" are fairly common in these regimes. Gui Minhai - for example.)
Past track record? I think the events you've mentioned are organic protests, but that is beside the point.
