It’s up to the core contributors of the collective, but I’d imagine @robbt & @paddatrapper would want to continue to leverage the services, features, community, and independence that Open Collective’s 501c6 org (https://opencollective.com/opensource) provides to LibreTime and thousands of other OSS projects.
That said, I think Fourth Estate could become a fiscal host (https://docs.opencollective.com/help/hosts) to support your custom branded LibreTime and related projects/integrations for SMB community news members and your upcoming College News Network.
This discussion touches on some related projects and ways we can leverage Open Collective.
