Earlier quoted context omitted.
This is decidedly ahistorical. Anonymous publishing was rampant in the 18th century. Broadsheets, pamphlets, political screeds, and all manner of printings were published anonymously or under pseudonyms in the time period, not least because there were consequences for putting your name explicitly on subversive materials.
Those ideas were still subject to a much greater level of peer review before they could be redistributed. You couldn't get a broadsheet or pamphlet in front of millions of eyes without the implicit approval of tens of thousands of voluntary distributors.
If you want a good sense for what newspapering was like in the early American republic, I highly recommend Richard Rosenfeld's book American Aurora (https://www.amazon.com/American-Aurora-Democratic-Republican...), the story of a newspaper that opposed the Federalists and the price its editor paid for that opposition.
