Yes, and then someone in China successfully extracted a key and built a "HDCP stripper" that double negatives the italic. They appeared to have taken the keys from few of something expensive enough so that it politically can't be revoked. Capturing HDMI also used to be costly, China solved that too few years ago. Compressed 2K capture dongles are $9 apiece. I wouldn't describe those as "tiny" barriers, though, it just wasn't up to faceless Chinese silicon gurus circa 2010.
