I feel this is the real selling point of democracy and free media, its hard for a foreign nation to buy an entire electorate.
Several nations seem to be setting themselves up for irrelevence by undermining democracy, usually at the behest of powerful groups within the country, but to do so they basically need to pay a bunch of people to tell lies. They've then created a network that external corporations and government actors can take advantage of. If the Russian news suddenly started telling the truth mixed with 30% Chinese propaganda, then to the average Russian that would be noticeably more true than what they are getting now.
Would the presenters tell blatant Chinese lies to decieve their people? Well apart from the chinese bit they obviously do, so you basically hope they're all actually insane true-believers, because if theyre just ordinary Russians spreading obvious BS in return for a decent paycheck then thats an obvious weak point for the nation.
And Russia knows this is viable, as they do it to other nations.
