When thinking about the Boston Globe faux-edition attacking Donald Trump, remember that if a conservative non-profit organization—let’s hypothetically call them something like “Citizens United”—published the same thing, liberals would want it to be illegal.
Of course, as Trump rightly pointed out in response, the Boston Globe is a “non-profit” organization (heh), but in the liberals’ worldview it is perfectly fine for a “newspaper” to produce a partisan hit piece on a candidate, but the speech of any organization that is not a certified member of the media should be heavily regulated by the government. The Boston Globe is a corporation too; I have yet to hear a Citizens United-hating liberal offer a coherent distinction between the political speech of a corporation known as the New York Times and non-profit corporation like the NRA that publishes the American Rifleman. (Though the New York Times endorsement of John Kasich does soften me a bit on the idea of authorizing government censorship.)
Given that most reporters in the mainstream media are rightly thought of simply as Democrats with bylines, it is clear that the Citizens United fanaticism of the left is an attempt to censor their political opponents.
