You could be leaking enough data about the hash or acoustic fingerprint of files users are editing which could be correlated with enough unique information to identify a user. On the positive side you could identify the user who created ransom_message.mp3 in the exceedingly unlikely case this scenario comes to pass. More realistically you could identify the creator of unpopular_religious_message005.mp3 or how about helping a repressive regime locate any and all creators of any of 385 banned religious or political ideas?
