In Russia it is a small government based operation involving couple hundred people. In US it is a wide scale, industrial operation, otherwise referred to as mainstream media and involves hundreds of thousands of people. In Russia the product is comments under articles, in US the product are the articles themselves. I don't think that we, in the US, are exactly qualified to complain about what the Russians are doing.
Just as one example, look at articles from 2008 to 2013 about Russia in the US mainstream media. It reads like hit job. There is not a single article published without a mention of some perceived problem in Russia, be it with Putin himself, so called human rights violations, free speech violations or corruption. Not a single article that would not spend at least several paragraphs on bad mouthing Russia.
And even if you say, those are justified, compare it to articles from 2008 to 2013 on Saudi Arabia, which has much worse record in every single regard. You will see the stark difference.
