This really upset me:

This is a completely unrealistic form of wishful thinking, and repeating it
won't make it more true.

At Dropbox I work with a large group of very capable developers on several
large code bases that are currently in 2.7. We are constantly changing our
code to make it more secure (there are several teams specifically in charge
of that). And yet porting to Python 3 is completely out of scope, for a
variety of reasons.

Please stop your wishful thinking.

(TBH, I expect that none of the changes to Python 2.7 under consideration
would  make any difference for the security of Dropbox. But neither would
switching to Python 3.)
