The problem is that those "signs" don't really point to it?

Like, new technology with bunch of hype appears, demand goes up, the hardware industry raises prices, prices probably won't go down to how they were before because the industry is pretty cartel-like.

That happens is every poorly-regulated market.

You don't need a secret cabal of people making computer parts expensive on purpose to make people dumb to have that make sense, and requires extra justification.
