Re: I'll say it again....
"For the Russian firewalls, are they really down to US belligerence or is it Russia's attitude towards the rest of the world? "
How long do you think any of these terrestrial firewalls are going to be effective for when you have not just Elon's Skynet in operation but several more providing resliience?
You can already send limited quantities of data via Iridium and other non-dish-based satellite services - it's how a lot of the stuff showing the Rohingya massacres got out of Burma in areas where the army would have pounced in minutes had they seen dishes pointing anywhere or anything resembling the usual videocomms kit. As it was, they triangulated on and killed several of the journalists by matching locations in the actual video footage.
It works the other way too - the USA's answer to the "great firewalls" has been to allow legislated monopolies which get away with both choking the living daylights out of connections, making them too expensive for most consumers and making it harder for middle america to reach neutral news sources (If you've ever spent time there you'll know that the average middle-american newspaper might have at best 3-4 pages of out-of-state news, with half a page of international news. Parochial is somehow not quite enough to describe it)
