This is the issue right there. Promise, there are no promises. Roadmaps are plans. Plans can change, unlike promises.

Kickstarter has promises that are (at least in theory) legally binding.
Early access is just buying a game as is. Thats it. If development stops the moment you buy a game thats fair game.
