A bunch of arguments they list on their Github page are strawmans. For example they say nobody wants to learn a new query language. I worked with Hibernate's QL as well as Ebean's QL and have to say none require any special training. Sure, the syntax differs somewhat but you can achieve what you want fairly quickly by looking at examples. And they all look like simplified SQL anyway. Also the page says one has to invent DAO layer but again - neither Hibernate nor alternatives require this. On the contrary, for example if you look at the canonical Playframework/Ebean examples they suggest static finders inside POJO classes, which work just fine.
