Well it looks like a mess and you can't do anything about it so here's what I would suggest. You already decided you want out so you have nothing to loose make a lot of noise and get everybody's attention, try to take the lead and make something out of that crap project. One of 2 things will happen 1 you will take the lead and save the project and earn a lot of respect from everyone by doing so or 2 and most likely they will treat you like the new guy with no experience and ignore your or fire you because you see things they don't want you to see and are being disruptive. From where I'm standing both outcomes seem favorable to you 1. you earn respect and maybe more 2. you get out of a failed project and dysfunctional community Good luck
