I'm with you that TFA comes off as mean spirited and needlessly so.

But having worked in large orgs in highly regulated and bureaucratic sectors (aerospace), sometimes things don't change until the process fails spectacularly.

Policy like "we can't accept email for security purposes" comes from total fucking morons in sub-C level upper management who have no insight into how the business actually works, for whom it's easier to say "no" than it is to say "yes".

It's entirely plausible that this episode (which I bet blew through a lot of PPNS budget in toner) caused some mid level manager to report the process breakage, kicking off a review of whether they really need fax.
