And yet there are pages of discussion on who Bail was referring to when talking to Mon Mothma or why Leia was present during the final battle.
Personally, I understood all of that just fine just as I understood everything you cited from TFA just fine. But you can't read this thread and think that Rogue One was 100% clear to everyone who saw it.
RO imo was clear as hell. It's two things. People not being die hards and not knowing exactly who Jimmy Smits character was. Also Die hard fans potentially looking too deep into what he said.
Some people thought he was talking about about Ahsoka.
