A small side question: what if Slack or Signal do delete or alter them instead? Not necessarily the parent company, just some rogue employee inside them. Oh, that's MIGHT happen with emails as well IF they are left on someone else server or some internal admin decide to do nasty things, but emails can be stored locally on ANY system, it should be used grabbing messages with the classic fetchmail and keep them locally, shared maildirs as well, just mirrored. A local approach to locally work and sync against the remote. Instead we keep choosing a SPOF after another with some that even state "that's for safety"... Try to imaging why we chose for instance to switch from classic cvs/svn systems to dCVS ones. Try to realize how simple is design desktops that works like desktops, of course you do not sync a copy of a multi-TB database locally but most stuff, docs, sources, mails and so can perfectly be local+sync issueless. Of course on a FDE storage. Why keeping modern desktops used as dumb terminals since they are far more capable than a classic dumb terminal and they cost as well because of that?
