fact is that if XD wasn't part of Adobe's ecosystem it would have never gained any traction. It became as popular as it its because its pushed down with the same subscription as Photoshop and the rest of the gang so it makes no sense for someone who has the suite to also pay for another product but it is a very badly made piece of software even though they started it from scratch and doesn't have all the baggage that applications like Photoshop have.

I do have XD installed just to view designs but I don't really design in it and what amazes me is how often it gets updated, almost weekly.
