It seems a bit backwards to massage the film to mesh with prior EU material since EU material will already bear that out in time as it does. If we say Poe left to join the Republic, even if that helps things that have been published so far surely it’ll come into conflict with future EU material.
Nothing wrong with making the change because you prefer it that way, but current EU seems like an unusual motivation.
Fair enough. There are still about 99 bigger problems in this film anyway 😉
