End users are using 6to4 and Teredo, if an ISP isn't providing their own 
relays, someone else is and the performance might be good or bad.

Same logic applies to Teredo as to 6to4 and why if you're an ISP who 
cares, you should run your own. Your customers are using both, whether 
they know it or not.
