i use gentoo because i love the package manager and how in control i am of my desktop and for servers even though not linux ive been using open bsd because of secure it is and lightweight helps squeeze out little bit more performance from mt shit vps lol
id say use the soical media in a browser and if u dont need a account use it over tor and all the people on telegram,messanger and whatsapp tell them about the privacy concerns with these apps and try and get them to move to simplexchat or matrix (especially if you self host) so theres no real drawback because they dont require any info of yours to work
