I think you misunderstand who we (i.e ALL pocketmine forks/spoons) rely on for updates and fixes. The only essential contributors are dktapps, Intyre & SOFe.
That guy actually has 5 accounts banned from the pmmp organization. He is no contributor. He is also banned from these forums and the old forums.
Example, all current developers are somehow magically taken away PMMP would stall for some time... but not long until someone takeover it, soon a new fork will be the dominant fork and we would continue life as normal the problem only arise when no one want/ready to takeover then we shall wait for eternity
