I would be more worried if only communist / socialist nations (you all know the ones I am talking about, not sure of a better name so calling them what they claim to be) were using it. If the NSA advises against Signal that might be another concern. It might mean a foreign intelligence has access somehow.
"Totalitarian" would be a better word, I think. This isn't specific to economic systems, it's about governments wanting to control the communication of their citizens (or subjects, I guess).

Or it could mean the NSA does not have access. They do have a history of wanting access to encryption systems.
Totalitarian is probably closer to the word I was trying to think of.
