Yes, HDCP 2.2 appears to be broken or otherwise defeated. Shortly before the first 2160p pirate releases, HDFury announced their HDCP 2.2 stripper. Definitely not a coincidence. Others have since been announced.
I don't know the technical details of how they are doing it. But it is pretty crazy that it has happened so soon into the commercial life of 2.2, even before the launch of UHD BD. I guess Intel did a crappy job of fixing the weaknesses.
