Well, since you mention it, Nikon and Canon also ripped off Zeiss's
patented coating process -- even Leitz didn't sink to that level!

You are, of course, correct, in saying that a well-constructed copy can be
better than a poorly-made original.  However, the Zeiss originals were
extremely well made lenses and were, in fact, superior to the Nikon and
Canon lenses in one important regard, that of the glasses used.  (The
initial production by Canon and Nikon did use Schott glass imported during
the War by submarine, but this had run out by the early '50's, and the
Japanese struggled a bit to establish domestic supplies of optical glass.)
The German lenses were made from a broader range of optical glasses and,
Postwar, Schott was breaking new ground in developing new melds.  The
Japanese were unable to compete in this and, for that matter, still allow
most research in this to be done in Germany or the US.  (Hoya and Zeiss
have an arrangement whereby Hoya references some of its production to the
Schott catalogue, for instance:  Hoya is pouring Zeiss glass, under license.)
