Copyright is broken

It now appears that Anne Frank didn't really write her novel, but instead it was her father, according to the company which owns her work (no relation to the Frank family). Never mentioning her father as a coauthor before means there probably is no credible source between the two is blatant copyright abuse, and just shows how the current copyright system is broken. Not allowing derivatives off of Anne Frank's work is going to seriously hurt writing about the Holocaust and World War II, and is not going to produce any benefit for society. Hopefully the courts in Switzerland will block this move and her book will be available for everyone.
