The problem is that the current era is one of underselling and knocking off open source projects. Yes, Josef Prusa has made a go of it with high end open source hardware, but Brooke Drumm shuttered Printrbot. The Moai secret sauce is the g-code conversion to galvo instructions and the underlying firmware correction of optical aberration. Like Formlabs, they are not going to give that competitive advantage up without something to compete against the knock-off sellers. They are a business after all. The Moai project was about bringing g-code to galvo-based SLA printing. Peopoly has done that well. If you want open-source resin printing, then DLP is the current answer. Someday, the Moai may be fully open-source (or will fork into an open source and closed source kit–unlikely at these volumes, this isn’t FDM), but unless you want to help someone build their next house, it is unlikely that you will see a successful open-source galvo-based SLA printer any time soon.
I think their “Linux Kernel” approach is actually better. This way there is central responsibility for the maintenance of the firmware and the controller hardware. I have seen open source projects forked-to-death and quite frankly that was unproductive.
