I believe you may not have correctly characterized the view that is critical of DJ. What I’ve read of Thanissaro Bhikkhu seems to imply that DJ is all too similar to what he terms “the state of non-perception,” and he holds this state to be wrong concentration:
The state of non-perception comes about from making your focus extremely one-pointed and so refined that it refuses to settle on or label even the most fleeting mental objects. You drop into a state in which you lose all sense of the body, of any internal or external sounds, or of any thoughts or perceptions at all. There’s just enough tiny awareness to let you know, when you emerge, that you haven’t been asleep. You can stay there for many hours, and yet time passes very quickly. Two hours can seem like two minutes. You can also program yourself to come out at a particular time.
This state does have its uses—as when you’re in severe pain and want some respite from it. As long as you recognize that it’s not right concentration or release, the only danger is that you may decide that you like hiding out there so much that you don’t want to do the work needed to go further in the practice.
I don’t know whether he’s right, but I do know that I would be unable to differentiate this description from what I infer DJ to be like. (Nor is his “easy” jhana all that easy, for that matter.)
