In the article, the author discusses the problem with the EDID signal. This, and the HDCP handshake are carried over a signal bus using the IIC standard. That standard was designed for signaling inside a cellphone! It was never intended to run between equipment chassis. The real problem with HDMI is that the standard was designed by a committee of apparent morons and was ill begotten from the start. We can only hope that time will replace it with something that actually works right. Meanwhile, we consumers must suffer with this mess. In my conspiracy moments, I imagine it was all done on purpose to create a specialty cable industry with obscene markups.
