Looks like your mail went into hyperspace somehow, it only just arrived.

EV is about accountability. The purpose of an EV cert is not to authenticate
the holder, it is to demonstrate that the holder stands a higher risk of
consequences that are designed to make it uneconomic to use EV certs for
typical Internet crimes.

They are certainly not the only security control that is needed in the
Internet, but they are a very usefull one.
