Have you tried hiring developers to do the work that you want?

I just cannot understand the entitlement of demanding some open source developer must do particular unpaid work that users are demanding.

With open source, you can fork the project.

It should be okay for an open source maintainer to say “no”.

It is not open source, because it does not meet the definition of open source.

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

Maybe each server is hosting a different area in the game, and they are connected by portals. Would need a way to transfer users and their inventory to another server.

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.
