HE.net run a perfectly good rwhois server which has my town, state, country
and zip code for my personal IPv6 tunnel, just the same as they have
full contact information for my HE-provided business IPv6 space.

The content providers are concerned about who is consuming the
content, not who is paying for it. Those needn't be the same people,
and given how careful people are not to share netflix creds with friends,
often won't be.

Netflix could stomp on credential sharing, but they don't seem to particularly
want to. Blocking a few VPN providers seems a figleaf to keep the content
providers happier while inconveniencing relatively few end users - anyone
who's using a VPN or tunnel anyway can probably change things around
to avoid the blocking with little effort.
