Yeah, the two steps:
* going into some internal directory and running a script based on the name
* deleting a bunch of directories
Seem like pretty bad ideas. Especially for software provided by a hardware vendor, which is probably a little clunky and inherently touches deep stuff.
But not including a removal script seems like bad form.
Edit: On the other hand, I don’t actually know for certain that the tool doesn’t have an uninstall script. Just, that the author didn’t find it. This seems worth noting because the author really wasn’t giving them the benefit of the doubt on anything, see all of the irrelevant complaints about animations.
I mean, there clearly was an uninstall script. It was in the app's Contents/Resources file, and it was called CleanupMagician_Admin_Mac.sh. Which means there was some intended way to trigger running it. Perhaps Samsung's instructions or their menu system weren't clear and they managed to hide it from him. But there most definitely was an uninstall script, and if he had managed to find the intended button in the interface, it would have asked for admin permissions and then done all the cleanup for him. The very cleanup that he complained about having to do by hand.
