If you can tell the President on Christmas Eve "Let's Go Brandon" which means something vulgar and you don't go to jail then you live in a free country
If you are incarcerated in a re-education camp because of your religion then you live in an unfree country
Everyone, the reporter included, knew fully well what the crowds were chanting. That phrase sums in 3 words how corrupt the media is to whitewash and censor any criticism of the establishment president and the mainstream narrative.
The US is orders of magnitude different to and better than China, but still has room for improvement.
US citizen: I live in a free country! Nobody will prosecute me if I go next to White House and shout out loud "<name of US president>! You are an old stupid son of a bitch!"
USSR citizen: I also live in a free country! Nobody will prosecute me if I go to Red Square and shout out loud "<name of US president>! You are an old stupid son of a bitch!"
Let's go Brandon is not widely known, I am inclined to think, to the typical audience of President's Christmas Eve address. It does not warrant any action because of this.
Edit: Ah, silly me. That was just a thinly veiled insult against China, the great big devil.
