HDCP can't really be stripped, if it's on then something is an HDCP receiver. For v1.4 signals you can probably get something with the leaked key, but not for v2.2 as yet.
HDCP itself needs to be licensed in order to generate it, and that licence is only available to HDMI Adopter companies. However there is code to get some chipsets to turn it on:

Grab it now before Intel deletes it completely.
HDCP is really a very ugly protocol designed just for anti-copying, I wouldn't build anything relying on it, and everything is harder with HDCP from an AV integration perspective. If you have long links that you want to secure, use something like SDVoE with encryption and authentication (bits are easily flipped in HDCP).
There are devices that will give you HDCP 2.3->1.4 conversion for compatibility reasons (or maybe wink-wink reasons), and after that you can use a HDCP 1.4 stripper. There are also devices that will strip 2.2 outright (they are marketed as HDMI splitters but, oops, one of the two outputs has unencrypted signal, an honest mistake); not sure about 2.3 though. Completely agree that HDCP makes everything harder, but in this scenario it would also make attacker's job of descrambling the eavesdropped signal harder. And this is after they have overcome packetization and spread spectrum hurdles, which the paper suggests is very challenging to do, so would be a (hacky) defense-in-depth for DisplayPort. Even more important for HDMI/DVI which lacks the aforementioned hurdles.
