Spoiler!

Lore wasn't dead, he was disassembled by Data and sent back to Star Fleet at the end of Descent Part II. Its more likely that he would have positrons available as opposed to Data who was blowed up.


I think its a stretch to say that in the period from the time that the virus was unleashed to now that the Tal Shiar who has penetrated Star Fleet wouldn't have stolen that secret.
