I’ve been working really hard to research and rank messaging apps by their privacy. The more green boxes the better.
I plan to turn PrivacySpreadsheet.com into a place for privacy data on everything from cars to video games. It’s all open source too on GitHub.
Not trying to advertise, I just put a lot of time into researching all this, and I want to share it since I think others could benefit.
Replicating all chat history + attachments provides a lot of resilience to the network from a node going down, but at the cost preventing to the home lab user from practically hosting a server which just means everything centralizes around Matrix.org, & when anyone on Matrix.org chats with you or your group, that metadata gets synced back to the central hub server once outwardly funded by Israeli intelligence.
