Then the encryption isn't worth the processing time. And as a 'legal shield' it seems like it will not only be utterly ineffective in court, but it's going to be cited as proof of Mega's ability to know what people are hosting, due their generation of a file fingerprint as a matter of course. They're going to wind up having to maintain a hash blacklist which is going to be just annoying enough that people aren't going to bother. It's a shame mega isn't just running an encrypted block-level store. They should have shipped client binaries that handle the encryption and key generation and simply exchanged blocks with Mega servers.
