*NED.
And I don't think this is enough to discredit them as not secure and private.
Organizations like the NED or the CIA benefit immensely from private encrypted chats for conducting regime change operations and preventing their adversaries from being able to compromise espionage cells.
Just as the CIA produces good intel for itself, despite being the world's foremost powerhouse at speeding misinformation, it is a simple case of interests aligning. They don't mind a few Western libs having off-the-grid discussions if it furthers imperialist and regime change projects.
...or they could be honeypots, we may never know for certain, even if I think it is far less likely than wanting to discreetly communicate with assets embedded in foreign countries. If Matrix was a CIA honeypot, it would work better.
Taiwan should be taking notes
