I believe this is a minority opinion, but I love XD.
It (1) does everything I need, (2) doesn't do things I don't need, (3) is fast and (4) is easy to teach other people.
Considering none of this is true of other Adobe products, it's not surprising that the XD product felt "out of place" to their executives. I imagine several SVP's are quietly relieved to see XD hit the bin.
