In the past (previous century, first releases) there hqad been some 
restrictions (i've forgotten which) that had to do with the fact that a 
third party was using context for a project and that we got notice that 
lawyers of that company would claimed copyright of context because it 
had become part of their workflow ... so, we had to make sure that by 
making context public it could not be used against us (like: we take 
context, add a few lines, and now it's ours). Then someone convinced us 
that people who 'd do such things would probably get themselves outcast 
from any community anyway, i.e. that there is some protection is being 
part of the tex community.

I think that there are still some recomendations with respect to not 
using the same filenames for patched files (simply because tex is always 
a large file infrastructure and we don't want to be bothered with 
support for such patched). AFAIK that is not much different than with latex.

Anyhow, license discussions are mostly wasted on me.
