I’m not seeing the problem from a pure capitalism point of view. If they want to jack up the prices on the latest fad, so be it.
It’s a fad like digital photography is a fad.
In Great Briton, ebooks are now outselling analog, it is trending the same here.
You can jack up your own prices all you want, what is illegal is getting together with your partners and competitors and devising a scheme to force the market price to go up. That is why OPEC and De Beers would both be illegal here in the US.
