Apple has threatened to remove Amphetamine from the App Store

I mean, on this point I'm actually inclined to think Apple's general policy is reasonable, even if it sucks that Apple is only now adding or enforcing this rule.

It doesn't want apps that jokingly call themselves "Crack Cocaine", "Crystal Meth", or "Mango Vape". It doesn't have anything to do with them actually promoting drug use, but it helps normalize illegal drug use in a way, while Apple wants to keep a "family friendly" approach to its App Store.

Honestly, if I were the creator I'd just rebrand it.

I remember coming across the app years ago, it wasn't obvious from the name what it did, and when I finally understood it, it just seemed like the creator was trying a little too hard to be "edgy". And if you want the widest possible usage/distribution of your app, "edgy" is usually not the way to go.

macOS ships with a command line program called "caffeinate" that disables the sleep function of the laptop. With this background knowledge I was immediately able to assume Amphetamine is a more powerful program that provides the same results. With this background in mind I find the name to be clever.

And if someone made yet an even more powerful program called cocaine, that would be okay too, because the name fits so well. right?

That's funny because Apple maintains Coca, which is the name of the plant source of Cocaine. The Coca plant is controlled/regulated by the DEA exactly like cocaine is. So by following Apple's example in Apple's ecosystem it is okay to name things directly after drugs.
