True enough, I only suggested that it was implied. Certainly the ability to bend lightning is not restricted to the royal family, but knowledge of how could probably be very tightly controlled. Overall the royal family (other than Zuko and Iroh) struck me as the types to consolidate power in every way they could, and while not specifically said, I would not be surprised in the least if Ozai did not perhaps make it a policy that non royal firebenders were restricted from learning it.

This is, of course, speculative on my part, but given what we know of the royal family, from Sozin, to Azulon, to Ozai, it seems like something they would do.
