"There is no reason for the open-source community to worry..." writes Daniel Stone, who heads the graphics team at open-source consultancy Collabora. Мfilion quotes Collabora.com:
Recently, Sean Paul from Google's ChromeOS team, submitted a patch series to enable HDCP support for the Intel display driver. HDCP is used to encrypt content over HDMI and DisplayPort links, which can only be decoded by trusted devices... However, if you already run your own code on a free device, HDCP is an irrelevance and does not reduce freedom in any way....

HDCP support is implemented almost entirely in the hardware. Rather than adding a mandatory encryption layer for content, the HDCP kernel support is dormant unless userspace explicitly requests an encrypted link. It then attempts to enable encryption in the hardware and informs userspace of the result. So there's the first out: if you don't want to use HDCP, then don't enable it! The kernel doesn't force anything on an unwilling userspace.... HDCP is only downstream facing: it allows your computer to trust that the device it has been plugged into is trusted by the HDCP certification authority, and nothing more. It does not reduce user freedom, or impose any additional limitations on device usage.
