House Redoran is adamant in their dislike of outsiders controlling Morrowind. So long as they rule the Dunmer, they won't willingly be subject to human rule. They're fiercely independant.

As to High Rock, they've been stalwart supporters of the Empire for centuries, that's why they wouldn't join Ulfric. Like I said, the human provinces will likely band together to fight the Thalmor, but beyond that Ulfric would have to conquer Cyrodiil at the very least. Even if High Rock joins (which I highly doubt) Cyrodiil wouldn't.
