The real risk for American broadcasters is not that dissent will be visible. It is that audiences will start assuming anything they do not show is being hidden

The modern Olympics sell themselves on a simple premise: the whole world, watching the same moment, at the same time. On Friday night in Milan, that illusion fractured in real time.

When Team USA entered the San Siro during the parade of nations, the speed skater Erin Jackson led the delegation into a wall of cheers. Moments later, when cameras cut to US vice-president JD Vance and second lady Usha Vance, large sections of the crowd responded with boos. Not subtle ones, but audible and sustained ones. Canadian viewers heard them. Journalists seated in the press tribunes in the upper deck, myself included, clearly heard them. But as I quickly realized from a groupchat with friends back home, American viewers watching NBC did not.
