Thanks for this, you were reading my mind. It was my intention to do a
little Googling this morning to find some decade-old news articles
supporting the claim that Intel was caught ripping off DEC.

Your very last line, however, is a little wrong. CSI (DEC) and
HyperTransport (AMD lead consortium) were designed to compete with
each other while getting a leg up on Intel (in those days, Intel was
making so much money selling CPUs and chip sets based upon FSB, they
weren't conscious of any alternatives). After the official Alphacide
in 2001, some engineers went to Intel while others went to AMD. As I
understand it, Intel saw these incoming engineers as interlopers so
any new ideas were met with resistance. This is one reason why it took
so long for CSI to morph into QPI which first appeared in
November-2008 on Core-i7.

http://en.wikipedia.org/wiki/Common_System_Interface
quote: Intel developed QPI at its Massachusetts Microprocessor Design
Center (MMDC) by members of what had been DEC's Alpha Development
Group, which Intel acquired from Compaq and HP. Prior to the name's
announcement, Intel referred to it as Common System Interface (CSI).

Many ideas behind CSI influenced successive versions of
HyperTransport. I can only "assume" that this was due to the influence
of the DECies at AMD (but this assumption is just conjecture on my
part)

Anyway, a wise academic once said "the victor writes the history" so
surely Intel would want to present a more honorable narrative. We
would all do the same thing in the same position :-)
