Apple has threatened to remove Amphetamine from the App Store

Next, some app named Nitrogen will be banned because it is related to explosives and therefore to terrorists.

Nitrogen is an element, and a very common one at that. Explosives are a fringe use case.

Amphetamine on the other hand has only one very well defined use case.

I get the reference to another similar app (Caffeine) but this is a step too far, indeed portraying a dangerous drug in a positive light.

I seriously doubt your nerdsniping changes the point of the original poster. Which you could easily figure out if you weren't so eager to jump upon every single minute detail and consequently missed the forest for the trees.
