The reason why 6to4 isn't working isn't at the content provider end.
If the content providers could flip a magic switch to make 6to4 work
reliably, we'd done it a long time ago.  But when the access network is
filtering protocol 41, for instance, what else can we tell the affected
end users to do, except to turn off 6to4 or IPv6?

Perhaps you will find these links enlightening:
