My manager (who uses Windows as a daily driver) overheard me recommending a colleague to install Amphetamine and gave me a very puzzled look. Another time I had to explain secops people why do I have an executable called "riot" on my machine (part of Apache Jena if you are curious). So I can imagine Apple just got tired replying to complaints (semiautomated?) from IT sec departments that Amphetamine has nothing to do with drugs and decided to force Amphetamine to rebrand instead.

PS: I vote for Redeye as a new name (https://en.wikipedia.org/wiki/Red-eye_flight, just as Amphetamine was used by pilots in the past https://en.wikipedia.org/wiki/History_and_culture_of_substit...).
