Sooo...if the Expanded universe doesn't matter, then when is Lucasfilm going to give me back a massive chunk of my money that I paid for all these Star Wars Books, Games, and Comics that I purchased with the understanding that I was reading what was happening in the Star Wars universe. Since I seem to have been immersing myself in a series of events and actions that transpired in a totally different yet completely identical universe complete with identical characters...hmm, I paid for Star Wars media, not 'It's just like Star Wars!...but not really, but we won't tell you that.' media...
Seriously, this is simply ridiculous.
Yeah, sure, whatever no extended universe, so then why set your story a few decades after the end of the last (chronologically speaking) movie?
You could write some really interesting stories in the direct aftermath of the whole Rebellion, maybe find out what happens after the Rebellion declares 'Mission Accomplished'? It surely couldn't just be as simple as killing one person and then the war is over, right? It would be more complicated and intricate, since of course a Galaxy spanning Empire would have untold millions of worlds and countless beings within it, surely they ALL couldn't have been oppressed slaves? What if some honest and good people actually liked the Empire? Maybe some people really did see the Rebellion as rebels and terrorists?
See how the galaxy reacts to this defeat of a tyrannical despot? Maybe something gritty dealing with Galactic Politics and the Rebellion trying to become a government fueled by the memories of how the Old Republic failed utterly while trying to grapple with the failures and shortcomings that restoring a 'pure' republic would bring back?
Or something philosophical dealing with the rebirth of the Jedi, seeing the Idealistic Jedi that we saw in Luke after he was trained by Kenobi and Yoda (Who gloss over all the slave armies, interstellar warfare, child slavery and brainwashing/indoctrination) while struggling against galaxy whose last description of the Jedi were ruthless killers trying to overthrow the government?
Maybe that would be a good idea for a story-line...something dramatic...
Oh, wait, I know, it's the old 'keep the name, but do whatever the hell we want' strategy. Never-mind my ideas there...I'm only a writer. Much better ideas come from Directors who specialize in using lens flare to give me migraines. Set it a while after and then the other six movies don't even matter, we can do whatever we want then!
ADDENDUM:
Hmm, and looking back on it, I may have just written an outline for a better trilogy then we're ever going to see...
