Another possibility, given the difficulty of finding good ways for the network to distribute rewards, might be found based on the versatility of the payments mechanism.
So rather than a network centric mechanism there might be one, or probably multiple, collaborative donate and distribute FOSS app and library apps which replace services like Patreon.
I imagine they will be new and imaginative ways to do this, and we already have at least one waiting in the wings.
Personally I’d still like to see something built into the network at least trialled, because that would be immediately accessible to anyone and everyone who uploads without effort, which is something no app based platform could achieve.
