Is there any provision in that license file that would prevent the 
publishing of that file?

One of the strongest ideas when its 20 year old boiler plate that hasn't 
a heck of a lot to do with todays tech, seems like making such a license 
public so it, and the entity useing it can be held up to a wee bit of 
ridicule, will be more force to get it changed than a 100K$ suit for 
damages because the product cannot be made to work within the terms of 
that license. They'll automaticly defend against the suit, but the bad 
PR will or should, make them take a closer look at that license.

Just a thought...
