The point here is that it's not a discussion of sound quality, it's a discussion of the claim that silver/gold wire has superior electrical performance. In this case, it clearly doesn't, it's a wire that's been intentionally contaminated. If you were designing a cable, would you want the more conductive material, or the less conductive one, assuming you were acting in good faith?

I'd want the one that sounded best.
As long as customers are making an informed decision on silver+gold alloy, and not buying it simply because "gold is better" or because "silver needs fixing," if they truly read the post and understand what is going on, then more power to them. I just would hate to see anyone getting tricked into making an uninformed choice. Chances are, the silver/gold cable is going to sound a bit different to someone who has read that page already. It comes down to efficiency, too - to get the same level of electrical performance, you might need twice as much 5% gold alloy silver as you would pure silver - which, in a speaker cable, might be a serious issue. A 15awg silver/gold alloy wire could potentially perform like an 18awg one (half conductivity. Crystal Cables for example are very small gauge as speaker cables go, their entry level stuff is 21-22awg for a speaker cable or less; throw the gold into the mix and you lose 20% IACS, making it more like a 24awg speaker cable:

I can't name too many 24awg speaker cables but even the most staunch cable haters agree that speaker cables have some limits as to how thin they can be:

It stops being a subjective appreciation thing and starts to be a case of the amp not being able to drive the speakers as intended. So, adding gold to an already thin cable makes a bad problem even worse, all under the auspices of improving the cable's performance.
Thank you for your altruism. There are lots of folks who frequent this board that need saving from themselves. It is, after all, an asylum.
What I took away from the blog post is this question - what relevant property, other than conductivity does the conductor in a cable possess? And how does conductivity manifest itself on the application side as anything more than simple resistance? It goes against the core purpose of a wire to alloy a pure metal.
We can all enjoy cables of all shapes and sizes, but using a super thin speaker cable that has a gold surprise inside is going to throw off the gauge/impedance/length calculators that people use to ensure their speakers are performing adequately.
