I don’t think TFA was ever on there.
Anyway, I don’t know how these deals work. But I’d trust reporting over speculation.
Well I still don’t know the specifics of the situation, but if this tweet from someone called Robert Iger is true, ANH will be on Disney+ (and one would think the others too):

JEDIT: According to Disney, all the films will be on there.
