You're a friend monocle. He was saying that he's tired of hearing beginners play the same song all the time. You seem to be taking his statement the wrong way completely.
He said it in an irrelevant and attacking manner. Its a good song to begin playing. I'd rather hear Stairway to Heaven 15 times a day than Crazy Train. Those are the 2 songs that most guitar instructors teach first.. Stairway to Heaven is a simple song because of the intro and then it relies on the blues scale for the rest. Crazy Train is the same, it relies on a blues scale that up until the chorus goes no higher than a G chord.
Tldr; easy songs for beginner musicians, no need to QQ
