Sensible conclusions by the author of the piece. In fact other than Andrew Rothwell, there wasn't a whole lot of sense being spoken. Nonsense claims such as "....looses clarity along the way.." and "...they believe that...inclusions...weakens the signal...." blah blah blah. These have nothing to do with proper engineering or science. There's not a lot that we do not understand about signal transmission and cables, FFS, it's the simplest part of an audio chain!!!
A cable, any cable (in analogue terms at least) is part of an overall circuit and as such the impacts of L, C & R will be the things that effect the signal. In most domestic lengths of cable with the impedances concerned from output to input, the effects are likely to be slight if audible at all. For loudspeaker cables, cable length, gauge and reactance can have a greater impact on what you hear depending on construction, loudpsekaer and amps being used (again, its's part of a circuit). There are obvious cases where getting L, C and R right do make an audible difference, eg, between a moving magnet cartridge and a phonostage, where capacitance matters.
However, just because this may be so, is no reason to decry using things that are nice quality if that is your want. Many of us take a little pride in what we have often painstakingly assembled or made, so adding things of a certain quality (ie anything but the ugly and cheap little shoelace freebee cables) at least satisfies our pride if nothing else. Chances are, it'll sound a little bit better too (ducks behind the sofa!)
