The author is an unreliable narrator. The very first thing, the location of the script, can’t possibly be true (the app itself won’t be in per-user support data directory). They conflate things, they definitely don’t know enough about macOS to know to use sudo. I mean, they even rant about bog standard localization files…
Sadly, there are apps out there whose installers drop helper apps in ~/Library/Application Support. Or worse: Eve Online actually puts the whole game there. The Eve.app in /Applications (or wherever you choose to put it) is just the launcher/downloader.
