I'd been thinking Telegram would be a sufficiently secure alternative, but as Western intelligence gets their hooks into that system I think we need to go self-hosted. Element is the biggest name here, but I'm curious what options are the best for a combination of both security and feature maturity.
I want to like Element, but the devs' refusal to implement multiple account capability is a constant source of frustration to me.
I haven't used that feature but a bunch of non-element clients seem to support that according to this: https://matrix.org/ecosystem/clients/ (filter by feature)
Of them, I would say Hydrogen web, and FluffyChat, are the most serious based on features supported and what I've heard about them. I haven't used fractal since before it supported e2ee though
Fractal is great if you use GNOME. Only downside is that it doesn't have a UI for spaces yet
good to know! as a discord/slack alternative that feature seems sorta important though
