Time Might Be Running Backwards Inside Black Holes

This was written in surprisingly easy-to-understand language. The original article[0] goes into a little more detail but mentions something fundamental about black holes that I do not yet understand:

"The so-called teleology of the black hole event horizon is an artifact of the way in which physicists define an event horizon: the event horizon is defined with respect to infinite future elapsed time, so by definition it 'knows' about the entire fate of the universe[...]".

Can someone explain to me why this is? Why infinite future elapsed time if you don't see black holes as holographic screens?
