Possibly. Disney may slowly be phasing them out so they can move the properties to their streaming service.
Personally I think they tried to do too much. Daredevil and Punisher are by far the best 2, and JJ is next though I think that show's episode limit needs to be 8 episodes.
Luke Cage and Iron Fist just need to be combined into an 8 episode show for Heroes for Hire. I know it gets good reviews but I honestly think LC is as weak as IF was. I'm fine with the character but both of LC's seasons have felt very dragged out.
