I don't think it's an issue of lies about why small MTUs are good, but the
fact that if joe random user is told "576 is good", then they assume that 
anything different is _bad_.  We all know that there's good reasons for all
sorts of different MTUs, mainly because of the different types of traffic you
could have - there's always going to be a tradeoff between efficient transfer
of large blocks of data and immediaecy (sp?) of response time.  The problem with
anything Microsoft may put forth is that it'll read like "576 is good.  It is
the best.  We do it.  So should everybody.  If 576 is good, all else must be 
bad."  And that's simply not the case.
