Point 1:
If I am Russia, and I want to manipulate online opinions, do I do that with a massive bot network from inside my own country?
Maybe, but more likely I want the traffic to look organic, so I want to have it come from all over the world including from inside the US itself. Knocking down a data centre would have no impact on me then.
Additionally, I try many approaches simultaneously, hiring actual people to run these accounts and spread my propaganda online too. As a state actor, cost is not really a concern.
Point 2:
If there actually was a reduction in the kind of traffic being discussed, there would be evidence elsewhere, like these right wing communities that people claim have less posts in them now. But that’s just not the case, the measurements that have been taken indicate traffic and engagement remains similar to a week ago.

Okay, so if you’re running VPNs everywhere, guess what? Those are just servers, so you may as well just run the bots directly there because the traffic looks the same either way.
And you seem to be saying that the best way for Russia to hide its activity is to have all the activity originate in Russia where its vulnerable to attacks like this?
Remember, this is a state actor. They have access to more ressources than even the largest companies in the world. There are certainly teams and likely organizations dedicated to spreading propaganda on social media. It would be very naive to assume that’s not happening, and that it’s just Russia doing it.
