Reading your links, the known footprint between these governments seems quite different. Russia seems unique in its usage of these media. Faking a chemical disaster in the US, attempting to incite discord by faking a police shooting video, turning their own special LOIC on a NYT reporter...in comparison, the writeups on other nations' efforts (that we know about) leave a lot of room for this to be a false moral equivalence at this point. This NYT story is a pretty big deal in terms of providing evidence to that effect.
