Conventional means. For a long time, it has been possible to strip HDCP encryption through analog conversion or other means, but legal threats have prevented the spread of this strategy.
Now Intel and Warner Bros. are accusing a Chinese company
In the complaint
In the Federal Court. The complaint stated that a Shenzhen company called LegendSky produces HDFury series devices, which are “mainly designed or produced for the purpose of circumventing HDCP” and “except for circumventing HDCP, they have only limited commercial significance or uses. The complaint cited many product descriptions, among which LegendSky showed HDFury as a way to access protected versions of content that is not protected by HDCP.
Piracy is not the only reason you might want to delete HDCP. Certain HDMI splitters have cancelled protection measures for simple engineering reasons, thereby avoiding similar lawsuits, simply because they did not promote the feature.

The plaintiff is seeking damages, fair relief, and an injunction prohibiting further sales of the equipment.
