Okay . . . so what's the point of arguing with me about it, if you think
it's all irrelevant? Aren't the legal ramifications of these licenses
sorta the point of discussing whether one license is "more free" than
another? I mean, sure, there's an ethical component -- but, frankly,
ethicality is not dependent on licensing. The purpose of licensing is
to manifest either ethics or personal desire for how copyrighted
material can be used *in law*.

Yes, it does. I've pointed it out as well. Thank you for the news

Now relate it back to what I said in a way that disputes what I've said
about it. That passage does not, in and of itself, mean anything about
whether a given piece of software is "Covered Software". To determine
whether or not some piece of originally foreign code is "Covered
Software", you have to determine whether it has become "Modifications"
or comprises part of "the combination of files containing Original
Software with files containing Modifications" et cetera.
No single clause in the CDDL exists in a vacuum.

I've been reading and quoting the CDDL quite a bit in this discussion,
and I've read it before. Thanks for the link, but I can find it via
Google when I need it.
