Madness. In a just world, that would be illegal without a court order.
If what I'm reading is right, Cogent is particularly slimy about how they use their network. They've apparently refused to peer with Hurricane Electric for years, at least as recently as 2018, for no obvious reason other than because they can't squeeze money out of HE. It was causing severe disruption to IPV6 networking at the time. They seem to have a long history of dropping peers without notice and fucking over whole subnets in what, to me at least, looks very much like extortion. They also lie about being a Tier 1; they don't provide proper IPV6 connectivity, so in the customary definition they're not a T1 at all.
Looking further into it, the company was initially funded by something called the Keiretsu Forum, a bunch of "investors". I'm going to have a dig around and see what connections they have. I get the feeling they're ideologically motivated in some way.
