If Symantec's request was granted despite not following the procedures, the
browsers who reviewed and approved the request share some significant
culpability too. Collectively, it's CABF's fault, especially since the
process is designed to be adjudicated in the CABF public forum by CABF

First Data is pointing to its request getting a different outcome from
TSYS. The reason for the difference seems to be, as stated by browsers now
and at the time, that TSYS' request _should_ have been limited to 12/31 by
the letter of the process, and so browsers didn't want to replicate the
mistake a second time.

However, that decision absolutely opens the Forum up to criticism, since
the Forum is responding to its failure to abide by its own process for TSYS
by penalizing an organization (First Data) that is neither the Forum nor
TSYS. CABF members, especially browsers, frequently point out that entities
that create risk to the ecosystem should bear the cost of that choice,
rather than having the ecosystem absorb that cost for them.

I think the Forum should give First Data the extension to their requested
date. I think it shoudl also consider updating the process to extend the
notAfter deadline to February so that future exceptions, if they are
granted at all, can remain consistent with the text. This way, the Forum
avoids the perception and reality of conferring competitive advantage to an
unaffiliated company, and the policy avoids being inconsistent with the
results of (as of now) 50% of its uses.
