Breaking HDCP is a lot easier than breaking the other things. You don't have to attack the torment nexus directly. This is not the most ideal option but it is information theoretically correct assuming your capture rig is set up properly.
You can only get a WEBRip that way, not a WEBDL, since you'll need to re-encode and introduce some generational loss. The gold standard for streaming piracy is stripping the DRM from the original compressed bitstream, remuxing it to mkv, and uploading that as-is for maximum quality.
