I know there are these slight differences, and I do not mean to imply that they are not important. But still, the JSON-LD model is clearly a slight generalization of RDF. It is not something completely different. It could be explained, for example, by saying that its the RDF model with two generalizations. (The bnodes-for-predicates generalization is already widely known in the RDF literature, invented by terHorst in 2004, and could be cited.) But to re-state all the rest of the model as though it was something wholly new, without any reference to RDF at all, is (to repeat myself) deliberately misleading. And I have to say, that your reply here seems to me to be an almost pure example of tendentiousness.
