And what do you know, one of them is right now disputing claims of being connected to intelligence agencies lol

That is not great evidence tbh. The one linked in the tweet you mentioned seems to be a well established organization, so you would need some pretty compelling evidence (ie not just someone on twitter said so) to create a convincing argument that they are fronts.
Also, some of the people/organizations making the claims are pretty sketchy: The Grayzone - Wikipedia
I wouldn’t put my trust in said allegations.
WTF, this guy Kit Klarenberg is a fascist idiot (which fascist isn’t one though) writing b^^ls^^t all the time. I wouldn’t trust him if he said the sky is blue.
Probably a better fit as backdoor.
