Obviously this means a bunch of drug companies went out of business or stopped producing insulin because it was no longer profitable to make?
If they invested the money they've earned by selling insulin at very high margins for many years into research (as drug companies usually claim), then they should be fine.
If their business model depended solely on selling a single product and enjoying the margins, then it's good for the society. Someone else can produce it.
Who would have thought that having a single entity(not focused on profit) negotiating prices for pharmaceutical products would benefit consumers. Well, except every single country with universal healthcare.
If I've correctly understood the messaging around "if they give it to you, they can take it away".
