There's a lot to think on. But the simple truth is there's much more research to be done. I understand that the word "scam" gets thrown around as easily as any other four-lettered words and emotions can lead to using the most damaging word to try and hit back, but there's no denying the fact that the industry is littered with way too many abandoned development - some due to naivety on the part of the dev, others due to cashgrab agendas. Going to have to walk down this dev's history and try and figure out why. I also understand that certain projects may have grown bigger than the original dev like ETH - there could be a whole team of devs behind the devs...
