Let's forget the hyperbole, and focus on the facts.
Unless someone has a contract to supply set amounts at set dates, then the seller can decide who they supply first. This happens all the time - if you imagine you get the same deal and consideration when buying one thing vs Amazon wanting to buy a warehouse full, you're naive.
With the masks, it's a sellers market. Even if people have contracts, the come-back they have, if any, is probably some penalty fees for late delivery.
Again, it comes down to the fact that certain people didn't ensure that they had adequate supply. Placing an order for something only when there is massive demand isn't ensuring supply, they are trying to push the blame onto 3M when the blame is with the states and the healthcare administrators who were all asleep at the wheel.
Guess what you need to do if you want to get priority even though you only thought to order late? You pay a premium.
You're listening to the guy who messed up try to push the blame onto someone else, and you're swallowing it hook line and sinker.
You should be angry at the people responsible.
