I've also had such an experience. Same with Realm.io. The developers get very dismissive with just about anybody who comes in saying they have a use case which doesn't fit the scope of what already exists. Meanwhile features/fixes sit on the backlog for years. I'm not saying this will necessarily stop me from using a project, but it definitely does not create any loyalty. Compare this to say Rails, where I've had really positive experiences with the maintainers.
