The response to this isn't driven by sincere dedication to the pursuit of objective truth, it's a reaction from traditional media and power blocs over the loss of their monopoly on soft power and setting the agenda. I don't watch RT and I am critical of their commitment to only giving representation to dissident voices of the west without the same criticism of Russia but I don't really think it's that big of a deal if Salmond hosts a show on the network. As an aside if I am watching the news in work I'll put on Sky News as a lot of decent new media commentators are invited on but to pretend the channels themselves present a serious challenge to western hegemony for example is laughable.
