I suspect it's because pullups are generally more useful and also because 
much of the development takes place at least nominally outside of the U.S. 
For various legal and political reasons, this is true of virtually all 
open-source video projects (Theora is the only exception that comes to 
mind, and even there there have been concerns over DCT-related patents).

In particular, the rest of the world doesn't have to contend with our 
crippled DVD players, which are probably the #1 reason for pulling down 
25-fps video.
