Signal is convenient and no doubt more secure than most conventional messaging apps. And it's kind of nice to see so many activists have made it their home, leaving WhatsApp or Instagram groups behind.
Yay 😺
But #Signal is not a #federated system. It's centralised with its base in the fascist states of America. That should set your alarm bell going.
Not so much because of the nagging feeling that there must be a catch. (Did someone leave a backdoor open?) 🙀
No, more because of control and #collapse. If a single company controls all our private communication, this means it takes only a single blow to wipe our networks. If Signal's services collapse, due to some natural or artificial catastrophe, we'd be nowhere and scrambling to find our bearings.
So, although I'm not suggesting people abandon Signal en masse, I do think it's wise for people to start exploring and experimenting with federated alternatives.
If in every community or #activist network there are a few people who know how to use alternative and decentralised messaging software, and willing to share that knowledge, set up some kind of fall-back, then when things get prickly there will at least be a known path forward for you and your comrades 😼
