Sorry for being nitpicky about the exact tool, my broader point is that "Foo" or "corporation" isn't always obvious and is sometimes someone/thing you've never heard of before and would never think to search off the top of your head.
But like where would it be found? People are saying gotchas to me but they are saying things like host files or other directories where one might find services stored on macos. These aren't in some cryptic areas is what I am saying. If you are familiar enough with the OS to understand the concept of launchd and background services you know about these directories and what they might contain. These things are where you kinda ought to put these sorts of services if you are to write that sort of service for macos.
And really, this is better than what I've seen in linux where everyone wants to be cute with their own hidden directory paradigms.
