It took me a while to figure out what is being disabled in the code and why I need to care. I care about privacy but I would like to understand what I am giving up. If I understand it correctly, the code disables 'Spotlight Suggestions' and 'Bing Websearches'. You can do it in the GUI easily. Just go to System Preferences -> Spotlight -> Search Results tab (uncheck the above 2). Bing Websearch is clear enough but it took me a while to figure out what Spotlight Suggestion is. It looks like it gives you movie recommendations. If there is more to the code, I would like to know what else I should disable. Also, ideally would like to know what I am giving up by disabling them.
