If there's one thing you can always count on in the Linux world it's that packaging can be a nightmare. The OBS Studio team are not happy with the Fedora folks due to Flatpak problems and threatened legal action.
That wouldn’t work. Flathub and Fedora Flatpaks have different goals.
Fedora Flatpaks must meet legal requirement set by Fedora, so no proprietary or patented software.
Flathub also encourages upstream to maintain their packages. But upstream may not meet the security requirements set by Fedora. Fedora has much stricter packaging guidelines which don’t permit vendored dependencies.
