Tod is correct.  HDCP is so ubiquitous that nobody even looks for it.
HDCP is built into every HDMI device made for years.
See these Vizio specs that actually mention it.

Von is wrong about HDCP being dead.  In fact it has already taken over.

Although HDCP is everywhere, it's up to content providers to actually
activate/engage it's protections.  That is also what Tod was talking
about.  Very little HD content (outside of Bluray) actually *uses* the
HDCP protections, likely due to the "backlash" that Von was talking
about.
