I'm assuming they acted rash and emotionally when they decided to make their own platform, and realized the task was too big for them to shoulder, so they went nuclear. It's not just the fluxer stuff, at least one of them also deleted their socials.
I think them deleting their apexsync discussion server before the release date (so people have no chance to switch over if they forget the name) is proof that the project has died. Or at least isn't planned to release any time soon after all.
