i saw one person do something like this: messages JOIN ME ON SIGNAL(or anything not owned by Facebook and amazon) IF YOU DON’T WANT TO WELL WILL LOSE CONTACT SO PLEASE JOIN ME
im not sure on how well this will work but maybe exclude you’re family but try to get them to atleast WhatsApp but even better a private messager also consider xmpp/jabber and matrix for jabber i recommend calyx institute jabber server
