But still, in a movie where Solo gets his name by a random imperial officer, I don’t get why formerly Darth Maul would be an issue… (it’s one of the very few things that put a smile on my face)
Because one is a random throwaway joke (regardless of how much humor you find in it, if any) while the other requires a crazy leap in logic which is so far completely unexplained and is connected to a major plot point.
Your comparison makes no sense.
