tl;dw: Johnson and Johnson is using a legal loophole to extend a patent on a life-saving drug, preventing generics from being made. Scientists estimate this will lead to 6 million more people dying of tuberculosis over the next four years, because they cannot afford the high-priced name-brand drug.
I work with TB on a daily basis. TB is heavily tied to material conditions. I have seen enough signs that I think it's going to blow up in the US in the coming decades. We are gutting public health and instead subsidizing companies like this to find better drugs. This will end up causing it to be something exclusively benefiting the rich, and not treating TB like the socially spread disease it is.
