The entire application process is a song and dance that some ghoul in a lab cooked up to break down and exhaust the unemployed because they like their warm bodies barely awake and low energy enough to never rise up.
People who do things they like for free are called "hobbyists". These hobbyists, unsurprisingly, only do what they want to do. And sometimes they don't want to make a GUI.
The fact that they share the results of their hobby for free at all is just a bonus.
Not significantly because I'm always stupid specific with my searches, but I do notice that roughly every 5 results they put something in that has nothing to do with what I searched.
