Why did R2-D2 NEVER tell Luke Skywalker the Truth about Darth Vader being his father or that Obi Wan wasn’t quite giving Luke all the details either?

Cuz we see at the end of Revenge of the Sith that C-3PO’s memory is wiped but not R2’s!

So he could have spilled the beans when Obi Wan gave Anakin’s lightsaber to Luke or anytime after that!

But there are actually 2 answers to this question.

And the first is R2 not really knowing that Anakin transformed into Darth Vader.

See, all R2 witnesses near the end of Revenge of the Sith are Obi Wan and Anakin fighting on Mustafar but only see’s Kenobi return without him.

At this point, R2 probably thought Obi Wan killed Anakin and wasn’t able to connect the dots with Vader later on.

But the second answer actually makes more sense but it’s in the now Legends book The Swarm War.

And in the book it tells us that R2 was programmed to not share ANY information to Luke and Leia about their parents to protect them!
