We have DMs with groups on Simplex. And hiding meta data is critical if you value security. Bill Binney, retired head of tech at the NSA, said meta data tells them almost all they need to know even if they can't read the actual messages. That's probably why most corporations will allow you to install Signal on your phone but will block Simplex installation. Signal is a meta data honeypot. I am still pissed that nostr, that advertises itself as decentralised and censorship resistant, managed to slap a "sensitive" viewing ban on one of my posts, that not even I could read and then deleted my protestation !? FFS !! Highly suspect. As it stands, Simplex may end up to be the solution
