... yeah I get it, but why is everyone pissed because there's people willing to pay too much for something. Hell, if I can sell something for twice as much as the next guy and get it, than why not? We all perceive value in different ways. That's the way it works in a free capitalist society where the pricing of commerce is ultimately driven by two concepts: 1) necessity and scare resources and 2) basic supply and demand.
We see that everyday, but sometimes we just don't like it. I pay almost 2 times as much for my dry cleaning at the place I go to just because I like the people there better. They speak English, they know name, and it's hassle free. I don't know if my clothes are any better off, but it's still worth it to me for whatever reason. At the same time, it's my choice to go there, and I'm glad I have the option. My wife thinks I'm an idiot for it.
The whole thing works both ways as well. At some point, I may go down the street and pay a lot less and others my do the same. At some point, they'll no longer be able to get the rates they're asking for. They'll either have to lower the price or go under.
If Dennon, Monster, or Kimber want to put a bunch of useless technology into a cable and charge an arm and leg for it, it's their option. No one's forcing anyone to buy it, just as no one forces anyone to buy a $25K pair of speakers over a $2.5K pair that 95% of people couldn't tell difference if they were blindfolded.
My only caveat is that they shouldn't deliberately and materially lie. They can talk about data sheets and prove that this measurement comes out better than this other cable (even though it may be meaningless in the real world) but they can't outright lie.
I for one like it when people put out stuff like this. I'd never buy it, but I think it's fun to look at and makes me marvel at the kind of money some people really have to burn. And that's the group you're talking about. No one is gonna be putting away a slush fund to buy a several hundred dollar network cable or gonna trade the weekend at Disney for it. You either have the money and don't care if you blow it or you're buy different cables.
