Artemis was never a "return to the moon" program. NASA had one of those; congress killed it and replaced it with a "keep shuttle jobs going" program. There has always been and will always be pork spending, but in this case keeping the gravy train going has been the primary if not sole driver, as opposed to programs like Apollo where it was a means to an end. People have known it was a problem from day one and probably most people thought it would get cancelled and replaced by something more sound long before this point.
