the part of the “conspiracy theory” about CIA funding is completely true: signal proudly say they get funding from the OTF, which at the time signal started was a subsidiary of Radio Free Asia, which started out as an open CIA project (before being relaunched as clearly still a CIA project but without the official acknowledgement).

I’m 50:50 on whether signal is a literal honeypot, but even if not it seems pretty likely that the US government wouldn’t have funded an app that could be used by people breaking its laws - let alone people actively organizing against it (foreign spies, domestic revolutionaries and insurrectionists) unless they were getting something pretty big in return.
