How can they *not* offer IPv6? Are they filtering our traffic?
What's stopping us from just asking ARPA for an IPv6 subnet and using it?

Tunnels are far less than ideal. We could just as easily setup one of the IPv4
address's 6to4 blocks, that way we get the most BGP-direct route possible...
If you're not aware of 6to4, it works like this:
For every IPv4 address aaa.bbb.ccc.ddd, there is a matching IPv6 subnet
2002:aabbccdd::/24 assigned and automatically routed to the same destination
(with an IPv4 wrapper around the packet, to get past any non-IPv6-aware
routers). Thus, if your IP address is 126.96.36.199, packets sent to
2002:0403:0201::1 will arrive at your system, even if your ISP is IPv6
