If Mozilla declines to make this exception, it will not be that choice
which harms Worldpay's customers.  It will be the numerous bad choices
made by Worldpay.  Worldpay has significant resources at their
disposal: in 2014, their revenue was 3.6 billion GBP and their EBITDA
was 375 million GBP[1]. If Worldpay cannot get new payment terminals to
their affected merchants in time, then they can overnight credit card
imprinters and their merchants can accept cards the old fashioned way.
If Worldpay does not want to take care of their customers, Mozilla
should feel no guilt for not doing that for them.

It takes far too long to deprecate insecure practices on the Internet:
consider 1024-bit RSA roots, weak DH, RC4, and MD5.  How many times has
Firefox (and other browsers) been forced to delay a deprecation in
order to accommodate the needs of large companies? These companies have
the resources to do better, but they don't because they do not see a
cost to continuing their insecure practices.  Instead, they are happy
to have the cost be borne by the hundreds of millions of Firefox users,
who are forced to use a browser that is less secure than it should be.
Bailing Worldpay out of the predicament they put themselves in will
reinforce the perception that there are no economic consequences for
failing to properly invest in security that affects the entire Internet.

No Firefox users will be adversely affected if an exception is not made.
But if an exception is made, companies will continue under-investing in
the migrations that are necessary to move the security of the Internet
forward.  That will harm Firefox users in the long run.
