Yes, it's a well-known fact that manufacturers will sacrifice all the goodwill they've accumulated over the years for a little short term profit. /s
I'm not saying none of them do, but you've made a heckuva blanket statement there with zero citation.
Nobody said they sacrificed any goodwill. The scarcity provides cover.
It's literally every manufacturer of everything ever. Not just now, not just this century or this planet, or even this galaxy. From amoeba loaning glucose to a neighbour, to a star granting energy to its flock, the universal truth is the cost is what you'll pay, not what it costs to make.
If you set your pricing by what it costs you to make, you're not very good at capitalism.
Prices also skyrocket relatively fast, and come down much slower, for the same reason.
