It really isn't. The BBC publishes wrong or hopelessly biased stories all the time, which is why the majority of the British population no longer trusts them. As for processes to get corrections, as with many firms the best way to get their stories fixed is being it to the attention of blogs read by the ruling party e.g. Fawkes. Using their actual complaints procedure rarely seems to work.

RT is Russian state media, thus its propagandist, its not a real news outlet. There is no "journalism" tradition there in terms of ethics, trust, standards, etc. It follows the party line and the Kremlin's needs, which currently are to make the US/West look as bad as possible.

An important caveat is that they also post lots of normal content, so that it's harder to argue that RT should be blocked outright, and harder to identify the propaganda.

RT wants to spread misinformation on YouTube because Putin’s government wants to move Russians to Russian tech companies that can be “managed”.

not defending RT, but I've been seeing it in NYT, Verge, Bloomberg too. That's more what prompted my question.
