Because it is not funded by Murdock, maybe?
Yeah because Putin is all kittens and doesn't want to distract from Russia's very real problems.

However, much of the funding to this organization, ANO TV-Novosti, is injected from the Russian Federal Budget (2.4 billion rubles in 2007).
RT has been criticized as having pro-Putin and Soviet bias, advancing conspiracy theories, featuring radical commentators and promoting an extremist and anti western agenda, including support for fundamentalist Islamic propaganda. Some of these allegations have been acknowledged by the TV station, claiming them to be legitimate for an alternative TV station
Alternatives are good, biased FUD for the sake of a nation states purposes is no better then that they claim to be an alternative to.
