So what are the vulnerabilities in Signal? And how is Olvid better?

I’ve been using nextcloud apps since setting up a home server, Deck has been pretty useful for me for compartmentalizing my work tasks. There are a lot of different apps you can set up, including a workspace clone, but none of them I would say are worth it unless you want to use nextcloud in the first place. There are ways to sync nextcloud with Google drive, but I haven’t tried it yet. If you have a raspberry pi you can install nextcloud using the nextcloud pi install script pretty easily. I ran it on a pi 4 without any issues for a few weeks before migrating it to an old nuc.

There’s nothing in the article stating such. Just that one of the women had become fearful of the world because of COVID.
