Nope.

Still *NOTHING* about the physical layer.
Therefore, NOT fully published.

Therefore, NOT open. NOT free (as in freedom).
Still CLOSED and PROPRIETARY.

Still NOT in the spirit of amateur radio.

PS When there are "reverse engineering" attempts published on the Internet, you KNOW that it is not fully open. You don't have to reverse engineer an open protocol, because it is fully described in published documents. No such documents exist for D-STAR. Such reverse engineering attempts DO exist.
