I support the existence of #Fedora #Flatpak repository, but I think that Matthew Miller is wrong attacking #Flathub because Fedora doesn't need to do that. You can support your own Flatpak repository saying:
-To better comply with certain legal issues (remind H.264).
-To better manage your security policies (against nobody).
-Flatpak is decentralized.
-To give a correct ecosystem for atomic systems.
-To give a better support for alternative CPU architectures.
