I see they’ve been recently working on the Uno part of things, which is the glue for everything, plus the community recently updated the logo hehe, so no I wouldn’t say its dead just yet.
In terms of new component/native stuff, hard to say cos that’s really up to the community now and no one can know if someone is working on something, we do need a more in your face community component/package list thats auto-updated and searchable. Kinda like an app store for components would be nice ~ https://fuseopen.com/docs/packages.html.
Agree with aeq. Fuse Open is definitely not dying but I think we, as the community, have to focus on the source code when fixing issues/making new features instead of using self-maintained packages.
