I don't know, but for the Emacs 20 part (20.7, installed on Solaris in
2000 according to time stamps) my guess is a combination of:

- lack of attention to the Solaris environment when more and more
  work is done on Linux
- outsourcing of BOFH activities
- hard to know what problems an upgrade would cause for hundreds of
  users; hard to know exactly *who* they are and what features they
  have come to rely on
- maintaining an existing development environment = bad career move;
  implementing new, complex, proprietary and expensive = good move
- the programmers who really care install their own newer Emacs and
  tell noone about it
- Emacs 20 is still a very good text editor

I don't think it's uncommon for organizations to end up in that
situation, unfortunately.  But I wouldn't want to live at the bleeding
edge either ...
