What are you on about mate. The one who brought the whole bukkit project down was one of the bukkit developers not Mojang. The bukkit developer had contributed 1/3 of all code to the project iirc and protested that Mojang now owned bukkit and DMCA’d the entire thing to hell and back.
At that point it was easier to kill of bukkit and start over rather than to de-tangle and re-write 1/3 of the code.
