Consolidation of Email Platforms Bad for Email?

I'm sure Dave Crocker has thoughts about this, but it has come up
elsewhere.  There are both positives and negatives about having such a
consolidation.  The positive is that it a small club can establish
ground rules for how they will handle various forms of attacks,
including BGP hijacking, DKIM, SPF, and other forms of validation to
identify fraudulent mail, etc.  Also, if you have a whole lot of
postfixes and sendmails running around, that's a whole lot of code to
patch when things go wrong.  A small number of MSPs can devote a lot of
time and paid eyes on code.  They can also very quickly spot new attack

On the other hand, that means that it becomes difficult to become a new
entrant, because one doesn't easily get one's mail accepted.  Lots of
grey/blacklisting (forgive the use of the term).  Also, when one of
those systems fails, it takes down a vast number of customers. 
Furthermore, it represents a *massive* concentration of private
information that can be monetized.
