Most people are in the dark about what college level music education consists of. If piano was being taught in a classroom, then it wasn't a music performance major program. Also, there are tiers of colleges, and a school with an easy music program for rich kids is not unthinkable.
I have two kids who are both music performance majors in college (yes, we had the conversation about jobs), and I'm a musician myself. I learned the scales in middle school.
A remote possibility is that this is a freak occurrence. I think you can't design a training program that absolutely bars creative cheating, without also degrading the program for the majority of students who don't cheat.
All of us could play in a lot of scenarios at the end of it.
But it just so happened the college at the small midwestern town I grew up in had faculty from Eastman, Yale, Stanford, NW… and the music department was unusually rigorous for the level of school it was.
People don't describe themselves like that. They rationalize why it's reasonable.
Folks are more likely to say "I didn't want to learn a regimented set of things because it interfered with my ability to compose freely and play fluidly instead of mechanically. Also, art is about collaborating with other artists to make novel things, not just to repeat stuff like a machine"
Maybe these days even "not everyone is privileged enough to be able to obsessively repeat the same exercises over and over again"
No one in the history of man has ever made themselves out to be villainous. This sounds like a Scooby Doo villain when unmasked. "we would have gotten away with it if it weren't for you meddling kid"
