This matches similar research I saw in the last few days on some other political topic (can’t remember which) were some of the most important and active tweeters were Russian on both sides.
Russia wasn’t trying to get Trump elected (though they HATED Clinton). They were trying to get America to fight with itself and sew division. They did a really good job.
I’m saying they seized on it as something they could use to push division between people.

These studies are seeing patterns in noise. That's why the narrative changed over time - it used to be "Russian twitter bots got Trump elected!" and now it's "they're supporting both sides .... to sow division!".
The former claim was extremely implausible but at least it had some sort of inner logic to it, in that Trump was more friendly to Russia than Clinton. The new spin doesn't even make logical sense. However it makes perfect sense if you're just picking random Twitter users and trying to explain their behaviour through the prism of some convoluted conspiracy.
