You might like to add a file about #InstantMessaging. Various free and federated #IM systems do exist, with hosting in many jurisdictions. E.g. #Jabber/#XMPP.
The only provider I could put on the list would be Signal.
The goal of the list is to list services, that even someone's Grandma, with no technical knowledge, could use. So I'm not listing self-hosted since it is not something everyone could set up, plus not everyone could even if they wanted to because of their local ISP.
If you could think of alternatives, I am always willing to explore them, and expand my list.
