And they could easily redirect HE IPv6 addresses to a IPv4 only
service.  This would satify both the content providers and the
customers.  It's not like there tunneled traffic is IPv6 only as
there has to be a IPv4 endpoint for the tunnel.

You can't argue that HE is too small to do this for as they are
targeting HE tunnels.
