As an OSS maintainer, a pet peeve of mine is when someone asks why something is a particular way, when what they really mean is "I don't want to configure it to my preferences and I want you to change the way this works".
The "why" question sets things up for the maintainer to be on the defensive, which implies that the answer needs to be well researched and reasoned, which takes extra effort.
Ultimately the person asking doesn't care about any of this, making the whole thing a waste.
