Because yang is lying. You could see how intimidated he was when he had a chance to talk. His interview charisma was nowhere to be seen on that stage. Just look at how his UBI proposal kind of fell out of his mouth vs how he normally talks about it. That tells me he was extremely nervous, probably too nervous to speak up. Now he's looking for an excuse to make up for his " deer in the headlights" performance to hold onto his base.

And let's not forget how well censorship plays with his base. He's been courting the "intellectual dark web" since the very beginning. Playing the victim of the big bad deep state is like cat nip to that demographic.
