What's missing from the analysis is degrees of imperfection. RT will tout the Kremlin line even to the point of being comical. Even if Assange's show doesn't contribute to this, he still serves to legitimise the rest of the channel. He is extremely naive if he doesn't think he's going to be a cog in RT and Putin spinning itself and Russia as a home to disenfranchised and persecuted western intellectuals - while conveniently not mentioning the fact that disenfranchised Russian intellectuals, especially of the journalist variety, have a nasty habit of dying young - which is very unlike their western counterparts.
You might feel that the viewpoint of RT is no less objectionable than the viewpoints of the other news organizations you mention. Others disagree.
