The speculation I've seen is that Cogent refuses to treat HE as a Tier1
network in v6 because they don't try to also be one in v4, but that they
should because HE's v6 network is much wider reaching and much longer
established than Cogent's. In any case, Cogent's refusal to peer with HE
over v6 has been very public and well documented. It makes Cogent
unreachable from a significant portion of the v6 network.
It has perhaps not been as well known as it deserves to be. Perhaps
additional publicity here (and any other relevant fora), might nudge
the parties closer to a resolution. The non-reachability of the
IPv6 C root from a significant portion of IPv6 space is not a healthy
situation.
The error is immediately apparent via DNSViz:

RIPE Atlas DNSMON measurement doesn't indicate this:
