@pj @fdroidorg @matrix Behind matrix: a company called New Vector Ltd, now also selling enterprise services. Compares to mastodon: Synapse is quite resource-intensive when you join large rooms, but it works. Client-side there is a lot of choice, but the only "good" choice is the Riot.im electron client. Safe: E2E is not the default, but it can be enabled, but if I'm up to date, no client beside Riot can do it. Still, I'm a fan.
