Not got around to trying it out properly yet. Waiting on new AMD GPUs, hoping for a low-end encoder or I ma get access to a RX 480.

What does Jellyfin use .NET for?

Godot’s MIT license certainly let’s you redistribute the engine as part of your proprietary game. However, it equally lets others redistribute their games under the same open source license, or even a copyleft license. So it’s spirit seems equally business, hobbyists or free software moralist.

Copyleft helps me by making sure my code can’t be included in a proprietary software. My code is there to be copied but if you make changes and redistrubte them then I get access to those changes. Maybe I use them in my software, thus improving it.

The purpose of copyleft is to ensure the freedoms and restrictions made by a license are enforced by copies/forks/derivatives.

Best to talk to people interested in contributing to see what they would think?
