Yes, but it isn't "the license of a Debian component", it's an external
patent. So technically it's not the software that isn't Free Software, it's
some external condition that would make it move outside of main. (yeah,
"non-free" is a misnomer)

That's pure lunacy. Fortunately, Debian doesn't have to deal with it.

As I said above, we have yet to see a solid proof that they have something
against all this software. With KDE we had the two licenses to analyze, here
we just have lots of hot air.
I'm CC:ing this to Richard, the release manager, his opinion on whether
something is release-critical is final.
