I don't have anyone to use simplex with yet. It was a struggle to get my family to use signal instead of SMS, and I'm not sure if I can get them onto a platform like simplex, even though it seems to be about the most secure platform available.
It's really tough to convince normie familiars about digital privacy issues. That's why don't even waste my time
It was worth the effort with my family, especially since we chat about guns and children. Guns are certainly watched in cheat text, and I don't want any pedophile pervs creeping on my young family members.
