The support-only or maintenance-only models are very rarely successful. There's also the dual-licensing model, where non-free licenses can be purchased which allow things that the FOSS license doesn't, like non/partial-contribution. AGPL seems even better suited to this than GPL, precisely because many companies would rather purchase such a license than expose the custom elements of their network services. IIRC that's precisely why Affero came up with this license for their software (in collaboration with the FSF, to ensure GPL compatability).
