I am just jumping in not to pressure you specifically to dump the source but in my experience in quant finance and music software development (hobby), I see kind of a tragedy of the commons especially in finance. If more people made their source available upon winding down a project it would drive down costs in the entire industry and indeed the whole tech ecosystem. Reimplementation saps alot of productivity from the economy.
