Wow, please provide those statistics somewhere. I am sure lots of people
would love to see this, especially with a small analysis of what the
traffic most likely is (the answer is most very likely NNTP).

Teredo has the same issues as 6to4: anycast in both IPv4 and IPv6 thus
you never know the path that the packets will follow, thus it is
horribly hard to debug; unless you have access to every single hop in
the path of course.
THAT is the reason why 6to4 and Teredo are a bad thing: debugging.
Over all these years there have been a lot of problems with those setups
and people keep on complaining as it is causing brokeness.
And no, there is no magic way to fix this, if you have it though, please
illuminate the rest of the world with your awesome idea.
