This isn't going to be popular, however getting away with something for a period of time is not the same as being approved/sanctioned/etc. In the petition the author claimed that the app "spontaneously began violating" one of the guidelines, when clearly it has violated it all along. Yet that disingenuous angle is used constantly when people get away with something for a while and suddenly aren't.
As an aside, it's interesting that anyone thinks that making a big noise about this will cause Apple to revert their stance (as app using a pill as their icon, naming it after a controlled substance, and using narrative like "the most awesome keep-awake"). That is improbable. It seems much more likely that Apple will be very certain this app is renamed, and the narrative changed.
>"When you leave your Mac idle, it smartly goes to sleep to conserve power and reduce wear and tear. But this can also stop a big download short or prevent a lengthy compile or render from finishing. Instead of having to periodically wiggle the pointer to keep your Mac awake, launch Amphetamine and rest assured your Mac won’t sleep until you want it to. Amphetamine sits unobtrusively in the menu bar until you Control-click it (or press Command-I) to kick it into gear. That’s it. Your Mac will stay awake until you end the session."
