Caffeine might be better in this scenario, but amphetamine has some auto triggers and custom settings for keeping the system awake but still turning off the screen, etc.
Actually you just made a pretty convincing case that Homebrew has similar issues. I am already not a fan of it because I have hit too many amateurish bugs, but now I have another reason.
By the way, the word brew is also used for other things, eg. coffee or tea, and homebrew is a common metaphor for other things where amphetamine is unbiguously one thing.
Overdiagnosis & misuse etc aside the number of people using amphetamines therapeutically may well outnumber your "unambiguous" cohort by a larger fraction than drinkers do alcoholics.
I didn't say use was unambiguously non-therapeutic. I said it was unambiguously a drug. There are no famous cultural metaphors analogous to "homebrew computer club" etc. It always refers directly to the substance.
Maybe you should consider that a close family member had problems with this very recently before you call me tasteless. It is in fact really fucking stupid that some privileged Mac programmer, probably young and of limited life experience, thinks that is a cutesy name for his (yes I am assuming male) project and not the name of something ruining a lot of lives, probably thinks it's hilarious and clever. He has no taste. Opiates also have legit use. I wouldn't name a project after those either. There is a thing such as tone deafness.
I take prescribed amphetamine [0] twice every day. The taste of the name is not in the name, it's from whatever else you had in your mouth at the same time.
