Yep. There was an incident with this in 2015 when a Netflix movie was leaked in perfect 4K, horrifying movie studios. They found out that the pirate had used a HDCP 2.2 to 1.4 splitter; and immediately sued the manufacturer of the device.
They then quickly settled out of court when the manufacturer of the device showed in their own licensing manual that downgrading the HDCP version for compatibility wasn’t prohibited. Oops.
