I think the sentence just contains very laid back observations of hypocrisy.
"affirms the publication's independence" = Says it's independent.
"expanding Defense Department oversight, introducing new restrictions" = makes it non-independent.
Conclusion: The sentence indicates the policy is hypocritical and built on lies. The sentence is not contradictory, the policy is.
Well put, totally agree! The key word here is “affirms”.
Here, watch; I hereby affirm that I am god incarnate, that I have no flaws, and that every unit test I’ve ever written has passed on the first try. It cannot be denied that I affirmed that!
