I think Reporters Without Borders is entitled to their P.O.V. about press freedom, but they are very likely wrong about the U.S.
No one is imprisoned in the U.S. for uncovering government corruption or for opposing administration policy.
Journalists who claim to have information on crimes but who claim they have some kind of "Journalists Right" to "protect sources" are sometimes jailed, but this is because the journalists are /obstructing/ justice, not because they are /victims/ of injustice.
Anyway, the Wikipedia won't be endorsing or condemning the RWB rankings, and the articl on [[freedom of the press]] should make it clear to readers that the US is widely regarded as tops in press freedom, having practically pioneered the concept.
