We didn't choose it.  ARIN and other RIRs started handing out that space, 
and if you didn't like it you were welcome to not have any more IP space.

There's a huge difference between getting a handful of networks to fix 
their outdated filters and getting "the internet" to all upgrade their 
software or replace old non-upgradable gear.

Lots of 2500s can't run that code.  Where can I get a 240/4 compatible 
update of c5200-is-l.113-11a.AA.bin?

Interestingly, my unpatched Ubuntu 7.04 notebook would let me install 
routes for networks in 240/4, but would not let me configure an interface 
IP in 240/4.
