I see your point and I actually agree that it probably would be better if this was either opt in, or at least have the two settings on the initial spotlight window so that you can immediately disable them without going to the settings. Also giving 'privacy' info for each spotlight 'category' is indeed a good idea.

May point about the script was more that it also just disables the two things listed in the initial privacy info given by Apple, i.e. "MENU_WEBSEARCH" and "MENU_SPOTLIGHT_SUGGESTIONS" and having informative text with screenshots to which checkboxes to unselect on the website would have sufficed. At least you wouldn't be executing code from some random place on the internet.
