Japanese Beethoven Admits His Flam

Mamoru Samuragochi, a Japanese deaf composer, has admitted that he didn't write his music and instead he hired a ghost composer for 18 years.
Many people including NHK and other media were not able to read his lying. His ghost writer said he even has hearing ability and cannot write music scores at all.
The big point of this issue is I think whether his works are good enough to play and listen to. I want to know how critcs who has approved his works before would make a comment about his pieces after reveal the fact.
