Did you read the part about *IPv6* traffic ?
Your link points to some IPv*4* relationship. Over IPv6, you get this :

Note the "Active Now" part, which is only active for Cogent.

And then, rather than taking QRator (which does a good job and has interesting information on a number of things - who buys transit from who *NOT* being one of those things - or at least not the public information) as word of absolute truth, did you test that bgp.he.net thinks about this ? Since HE is one of the parties, it does make sense to check their tools to see their point of view.

Long story short:
 - Free.fr in known in France (where I happen to live and work) for only having Cogent as a transit for the last few years.
 - they are also known to peer (like "only exchange own routes and customer routes") with some "very big" networks (usually called "tier-1") : level3 and zayo among them.
 - Cogent and HE over IPv6 ... I suppose everybody knows the story.....
 - Free.fr depeered he.net about one week ago...

There have been some exchanges of tentative traceroutes in both directions on FRnOG (French NOG) and things are clear : free.fr and he.net cannot exchange IPv6 traffic.
