   And it is not released.  That's the key.  Internal use.

If I give you a copy, it is distribution.  The whole concept of
internal `use' is bogus.  I can claim that the whole world is internal
for my use, and then simply refuse to release the source to anyone,
since it is `internal use', if one would follow your thread.
