While I agree the author of the article is either ignorant of or conveniently ignoring the fact that the West has certainly done plenty to "...fight on the battlefield...[of] the internet", I also think it's a mistake to simply refer to Pravda-fr.com or Storm-1516 as merely "the other side". It's manifestly propaganda.
I have lots of energy for talking about all the messed up things the US government has and continues to do, esp. in the information space. I just don't know why we can't talk about Russian or Chinese imperialism or propaganda without doing so. It's not zero-sum; saying bad things about Russia is not saying great things about its enemies, and vice-versa.
