Given the fact that your first paragraph says the same thing my first paragraph does, it's unclear to me what point you're trying to make.
The intern in question had no part in making Google the size it is and was most likely not offered much choice in the way of team or project assigned, so no merit or effort was involved in either of the two. Which part would you like to dispute?
I dispute the part where you say she shouldn't get any credit for her work because she did the work at Google.
If you're going to make that argument, nobody at Google deserves any credit for anything we do. That's not how we normally measure impact. We all stand on the shoulders of giants, but putting those resources to work effectively still counts.
