Spigot Long Live?

Is Spigot dead? they are still updating and have developed a SpigotPatcher

It’s updated via binary patches, so their updater can push updates without handling the code that is DMCA’d, so it’s still alive for now.

For now? or will they see this through to the futre

No one can say. It’s possible that via enough binary patches that DMCA’d content may be sufficiently removed and they can be re-instated the right to distribute their code, but no one can say if that will happen before they give up and let another project take over.
