They're too young to know any better. ;)
Most of the media we grew up with that would celebrate and cover the saga, but also cast a critical eye at it are long defunct. And official Lucasfilm media outlets aren't going run anything remotely critical. I'm not sure how many younger fans get info from anything other than the net these days.
Guess what I should have said is, did Tarkin know Vader when he was a Jedi?
