In response to an actual threat from a centralised service being used for discussion of a particular privacy and security focused project, I set up a secure p2p chat group using #Jami yesterday. It quickly had five users and continues growing.
Already one person is pasting swathes of text from DeepSeek and following my complaint about that, another suggested he set up a Google Drive for sharing such stuff. 🤦♂️
These are #privacy aware people. We don't stand a chance.
