I’ve noticed that some “mobility” startups are using Linux. E.g. companies working on electric or automated vehicles.

Yes, but does that still count as “modern”?

BTW, there is a miniflux package in Debian testing / unstable: https://tracker.debian.org/pkg/miniflux

I’m also interested, but I haven’t kept up with the project. It sounds nice if data can be shared between apps, rather than each app just managing its own tables in a database.
