I don't understand... If you're accusing someone of "blame shifting", presumably you can identify where you think that is being done.
In this case we have a payload that apparently failed to cleanly separate from the payload adapter (according to a variety of sources). Both the payload and the payload adapter were made by Northrup Grumman, not SpaceX, and the two were mated together by Northrup Grumman, not SpaceX. Do you consider it "blame shifting" to point that out?
It’s weird that even your reply seems to assume it’s SpaceX’s fault. Why? (“I don’t like to see SpaceX fail...”)
