I never said he did. Filoni didn't like it (which is strange, because she should know about the Sith spirits in the EU, which he claims to know so much about) and later on Lucas changed his mind, after initially changing his mind.

Also, the dialogue you refer to is from a cut scene, a scene that is therefore not a part of the movies, which is my point. Lucas just doesn't stay consistent at all, except for this. So far, not one instance in Lucas's films or series says there's no such thing as a Sith spirit. What we do have, is the Dark Side manifesting on Dagobah, that's just a small step away from having actual Sith manifesting.
And what do you call the Son channelling different Dark Siders in his speech? Isn't that a very noncorporeal and spiritual aspect, even of the Dark Side?
