If you really think the main reason of community being decreased is developers getting greedy, then you should carefully collect your thoughts once more.
Anyway, it seems that it's once again all about Interlude. Except for his ungrounded reference to C4 that related projects have not developed a lot these past years, Tryskell might be right on the idea of choosing another chronicle.
If by any chance I was too much used to Interlude and wanted to develop something, I would probably try a C5 project and especially now that there is a working patch. If you carefully think about it, despite being very similar, many complained about features that were Interlude - specific over the years (augmentation system, shadow weapons, dinos, etc). Also, its client is as customizable as IL due to the existence of interface files that are missing in older clients.
The first step for this would be downgrading an IL project and adapting login server Init logic from a C4 project.
Might be bad as a concept, just throwing one of my ideas on the table.
