Fedora threatened with legal action from OBS Studio due to their Flatpak packaging
(www.gamingonlinux.com)
I answered most of this in the other thread, but I am aware that anyone can make flatpaks. What I meant is that flatpaks were supposed to make it easier for devs to get their software to end users by allowing them to not have to worry about distro-specific packaging requirements or formats.
But when someone else takes it upon themselves to make broken flatpaks, ones that you've requested they stop doing, now they're making things worse for everyone involved and should be considered a hostile fork and treated as such.
