Not quite. What he says is that "Although the wire may not corrode any further, it doesn't inspire confidence, particularly if the insulation comes close to the connecting terminals." He does not state that surface oxidation of copper wire will make any impact on the sound you hear. Nor should it.
As to buying wire because it is "only" $2 or $5 per foot, that is still silly unless the look of the wires behind your speakers is important enough to you to justify the extra cost you are paying. You can get decent, cheap, speaker wire at places other than Home Depot for 40 cents or less per foot that will not later turn green.
And while I have heard any number of people claim that they heard
a difference in differently priced wires based upon A/B testing, I have never heard anyone reputable claim that there is a measurable
difference in wires of the same gauge, regardless of cost. I have in fact heard many reputable people say that there is no such measurable difference. I'll trust measurements, over what someone thinks
they heard, any day.
