TV networks charge for advertising, pure and simple. When jackass gives a speech its advertising, pure and simple. That being the case I don't think that can actually be called censorship. This would be especially true with lies as they sure as hell can't be construed as something that is of any real importance.
I do not, for instance, listen to anything Jackass says because it has nothing to do with anything but himself. Same holds true with Kellyanne and the the other spokesperson. Waste of time. I treat ads the same way. If any of them say anything that actually has content of interest its always addressed by the talking heads so why bother?
The problem with doing live truth checking is that errors might occur due to time constraints which is, I suspect, why we don't have something like that right now.
