Name and shame the people who failed to respond. Heck, you can do it
right here. Included their contact info, curriculum vitæ of everyone
you can find who's involved with this horrific bug, etc., etc. You

Make sure *everybody* knows that the bug is in the ArcGIS software.
Make sure they let ESRI know loudly, publicly and frequently that the
problem is on ESRI's end.
