You can believe Morrowind is part of the Empire if you so choose. But overlooking the evidence, I don't see any reason that it would be. No, but it lists it with the other provinces that are still a part. All others it says "are no longer part", until it gets to Morrowind. Given this, and the lack of evidence against it, I believe it is still a province of the Empire, at least up until the events of Skyrim.
