I mean the mainstream actually secure ones.
Signal, Threema, SimpleX, etc.

I guess I need your definition of actually secure
Like a team of dedicated specialists that pour millions to billions into protocols that are high level encryption, or SimpleX where it's like a Terry Davis level Schizo dude.
Like I don't feel that Twitter, or Nostr DMs are ACTUALLY "secure" even if technically they are.
They just don't have that feeling of security.
