[Dracus]

riddle me this:

The enterprise comes across a race that has both cloak and holo deck tech. They don't try to trade for either.
Yet they do trade the holo tech to the klingons without even asking the aliens if they would allow this.
Now lets jump 150 years into the future. kirk's time. The Fed has neither cloak or holo decks. The klingons have cloaks but no longer use holo desks.
What happen to the holo deck tech taht was installed on the klingon cruiser? did that captain not share this tech with the empire and it was lost?
