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.
