not all but most due to financial reasons.  And generally it makes
sense, however with really high contention rates the odds of multiple
people consuming all the bandwidth at the same time goes up.

Discussing duplex I agree there is no reason to discuss it, anyone who
knows enough to understand that it means that you really have half the
listed bandwidth when doing symmetric traffic would know that is just a
property of wifi.  

By saying that there isnt a reason to discuss things because customers
of WISPs wouldnt understand network properties is implicitly stating
that if you use a WISP for service you are clueless.  This seems
counterproductive to saying that its a good topology if only unclued
people are to use it and all the clued people go elsewhere.

But when it comes to a neighbor with an AP its not always as easy to
indentify the exact reason for the interference, especially if as you
say its all upto the guy in charge and that the people on the other side
of the fence wont understand about some basic things like contention
rates.  The guy in charge cant possibly be expected to manage a network
AND go to each customers location to identify interference and find a
channel that will be clean for all customers.
