I checked out other "free speech" sites which regularly publish misinformation and lies (yet still insist that they are publishing the truth) and they still have ads. Breitbart, Newsmax. Alex Jones infowars platform primarily exists to sell supplements. Even Coast to Coast AM, the ghosts and goblins show, still runs ads.

Plus you have to consider that there is big money to be made lying to the public. For instance the Koch brothers spend a pretty penny funding climate denial.
