CPB was established by congress in 1976, and NPR/PBS was established by congress under the power of the CPB.
After the loss against the CFPB, I see the likelihood of this EO going anywhere to be close to zero.
One thing though, is that the language of the CPB law requires the CPB to be non-biased. We already had congressional hearings which pretty much make that a farce.
It will be fun, however, to listen to NPR and PBS to defend the non-biased nature of their programming in court under oath and subject to perjury if this makes it to trial. Will make for fun headlines and sound-bites.
Just imagine how much fun it will be to use AI to come up with fun trial exhibits. Simple word diagrams that show the propensity of words used in the same sentence as Trump versus Biden would be absolutely freaking hilarious.
Imagine a diagram that shows top 5 words related to Trump to be: fraud, illegal, impeached, Russia, and lie; and top 5 words related to Biden to be: sharp, competent, truth, popular, protector.
It's a simple algorithm that wouldn't be hard to write with all of the data. And you could share the algorithm and open it for cross examination. And it is a method that is scientifically accepted in the media industry.
It takes a special kind of brainwashed useful idiot to politically defend government fraud, waste, and abuse.
