Maybe you, but not Roger Moore. He and Sean Connery are really good friends. Besides, to most everyone--Moore included--Connery was the best 007, so why begrudge the man the opportunity (after a 12-year absence) to return to the role that made him famous and that he did so well? Also, it was only one film. It wasn't like Connery was going to compete against Moore year after year after year. It was a special one-off production, no more, no less.
I enjoy Connery as OO7 as much as anyone else, but during this whole ordeal I think Connery's behaviour really wasn't a credit to him. Perhaps had the movie turned out decent it would be easier to justify the existence of NSNA, but as it is NSNA is just a reminder that sometimes never should mean never.
