From my personal experience I probably open my glovebox four times a year. How many times do I look at my glovebox? That's much harder to estimate but I'd guess dozens. Do I like a clean looking dashboard? It was actually a major selling point for me when I recently went car shopping. People obsess about how their cars look on the outside but how things look (and thus feel) on the inside is more important.
A glovebox latch only minimally affects the look and feel but I don't find the tradeoff that automakers have chosen as obviously bad as the author.
