Why does it even matter wether it's a honeypot or not?
The client app code is public and auditable. You can even use a fork such as Molly. The client uses standard encryption cryptography that anyone can verify.
The only thing you might giving up to a potential honeypot is metadata. Is that bad? Yes. Is it still better to use Signal with normies rather than Telegram, iMessage, Facebook, whatsapp, etc? Absolutely.
Normies won't use SimpleX, Threema, Session, Matrix or XMPP. If you want to be a social human you need to compromise and just be aware of what you are potentially exposing.
