We did learn (partly). Everybody who was sane decided that the whole id of a 
bloated suid sendmail binary (also deamon) was a spectaculair bad idea, and
jumped on board Wietse Venema's Postfix (the MTA that was explicitly written
to be a secure, sane, save replacement of sendmail (some people choose DJB's
Qmail, which is also ok, but Bernstein's attitude complicated things). 

Then there were people that didn't learn, and although they choose a 
replacement, they choose something with exactly the same bad design (Exim).

So, yes .. the people that where affected *did* (mostly) learn from the 
Morris worm.

Same story with BIND (although BIND is not so crappy as Sendmail was).

The Windows world was a bit later, because Windows Sysops are more likely
to be sheep that will run anything as long as it's made by MS, no matter 
how often they get burned (IIS). (To be honest: Windows sysops know that 
they are payed to run and maintain MS products, not to make sure that the
best choise for the organisation is made. That choice was made by upper 
management).
