Cuz they had to beg the US gov for them; they are pretty much free to use under the condition that you do not critize the government's foreign policy or the army itself.
So if you want to make a war movie that is critical of the government, good luck.
And thats just one example; there is much more regarding all the "experts" send on television to talk about this or that country that happens to be at odd with the Washington dictatorship.
I'm sure this legislation will be almost immediately overturned by the courts. It has severe first amendment and fifth amendment problems, along with possibly being an illegal bill of attainder.
