Problem really is that they've damaged trust how I've never seen it before in a project that is no scam. Will be very hard to heal...
Agree with that on 100%, though I'm not so experienced in crypto as you but I dint see such project management behavior too from the my very beginning in crypto world. And yes it will be very hard to restore confidence, but it is possible I think, it will require a lot of hard work but it is possible to do.
