'Ideals' are mostly platitudes that have been set in concrete. They are at their best vaguely identified landmarks to which we can refer, usually as it suits one particular political purpose or another, as we journey separately and together as members of a society through the continuum of time and space.
Clearly, the Constitution of the U.S. bars government from interfering with "the press." For private entities to set rules about participation in them and to boot those who do not follow those rules is not a violation of the First Amendment.
As for freedom, it is the product of justice, not its source, or predicate, or foundation, etc.
