This is just supply and demand at work, and is not unique to just processors--it can happen in almost any industry. I've personally seen it with automobiles, automotive fuel suppliers, and medical supplies such as masks and disinfectants.
There are actually some laws that protect against this sort of thing during times of natural disaster, war, or a pandemic (like the one we are in right now). I would research the regulations and see where these companies are violating these laws. Then I would get in touch with the regulating agencies and report them--not just once but every single day until they're sick of you. If you've done your homework and they're violating the law and you keep pounding on the enforcement authorities to do something, in a few years you will see how these companies got busted. But in the end the companies know how to thwart around these regulations too, so there is a cat and mouse game at work where the companies are getting rich and it will cost you to pursue them. It's the terrible downside of a trusting economic structure that depends on people doing the right thing and third world minded cheaters entering that system and blowing through every loophole and getting rich in the process.
I'm pretty damn salty about this myself because I was once cheated $58k by a company that thrwarted FTC rules and got away with it, harming not only me and my business partner but many people, and to even a much greater extent (most lost well over $150k upwards to $250k+). An environment of regulation with enforcement is the only way to combat this--we've got the regulations, but enforcement is dwindling as the resources are getting overwhelmed. If enforcement isn't brought back in full force soon, it will be the third-world open air 'market bazaar' atmosphere with all these shady people doing whatever they want to. Can you tell I'm mad too?
