How does it push the limits of enterprise level support?
And I don't think they'd need sponsors but volunteers to host the CI machines. Tapping into the community to provide those could possibly get a few. If effort were put into using some content addressed network, distribution of packages could further be spread.
And if radicle finally supported large repositories, it could actually be hosted there and distribution would happen across all nodes willing to host the project. But that's not possible yet.
A lot of effort is being put into building a ecosystem for a proprietary Microslop platform. It's a pity.
