Change Fingering on Repeated Notes?

To change?
or 
Not to change?
That is the Question!

After one of my students wondered why the fingering in Bach's Minuet in G Anh 116 is so complicated, specifically regarding the finger subs on repeated notes,  I did a bit of digging hoping for a simple video explanation to add to piano lab for my student regarding why or why not to use changing fingers on repeated notes. Instead, I found the controversy is alive. 

One video asserts 2 Reasons you MUST change fingering on repeated notes!

Whereas this video leads in with the opposite stance.

STOP changing fingering on repeated notes!

He includes compelling "evidence" from a Lang Lang performance.

I wonder, how would you respond to this question? I'd love to hear your comments on how you approach this topic with your students!
