Differently, because that's a poor analogy. Trumpets are horns, guitars are stringed instruments. Now, if they called their trumpet a kazoo, it'd be time to throw down.
Glue pizza might actually be better. Ask yourself why anyone would need to make cheese stick to pizza. Because that's not really a typical culinary issue. So, the answer came from practical effect strategies for a commercial cheese-stretch shot.
Now, I'm not saying that there isn't still an issue with this type of misunderstanding. But, it's not "hur-dur, just glue it" that everyone always paints it as.
It's more interesting than that and raises issues about how questions are framed and how answers are digested.
Not nitpicking at all, it's fighting disinformation.
