Specifically what I chose US (allies implied), China, and Russia. These should be three competing factions.

I think even Russia and the US still do intelligence sharing on a lot of stuff - and that's before you consider that the US seems to be in everybody's networks anyhow, so non-sharing is probably just sharing with a bit more skullduggery.

I don't think they share on the bulk data. I would highly doubt they routinely cooperate on cyber crimes given Russia's stance on the matter (basically encouraging it).

Russia and China are allies. And I'm not sure if Beijing would even be interested in spying on TOR users since it's blocked so thoroughly it's basically unusable for Chinese residents.

I don't know they are that aligned to be sharing bulk data like that. I don't think the are considered formal allies.

China is for sure interested in spying on people in the US. I'm not sure if TOR users are of special interest though.

China and Russia are decidedly not allies.

They are neighbors with some overlapping interests and sort of similar goals if you squint. It wasn't very long ago that they were killing each other over border conflicts and annexed territory.

China right now is just using Russia for cheap energy, they don't actually care about the health of the state.

>It wasn't very long ago...

If that's how geopolitics worked China would still be an American ally, vice versa. But alliances can change. Once an enemy always an enemy isn't a thing.

>they don't actually care about the health of the state

That's true but it's not a requirement for Xi to care about Russia. In fact I'm very sure he doesn't care about the Chinese people either. Russia needs China and the CCP uses Russia, not just for cheap energy but for fighting a war that many Westerners haven't even realized that it has begun already. Russia and China have a common enemy, that enemy is NATO.

I get scared reading that wiki page. The fact that the Australians are powerless[1] to stop US operating Pine Gap on their own soil, says something about how important the stuff the NSA & co. is doing there. (Surveillance) Horrors beyond our understanding.
