I don't think this encryption is supposed to provide plausible deniability in the most general sense. Stuff was DMCA'ed from megaupload all the time, but that was never a problem. There were many many many uploads of the same data and you could always find a working copy. There was a lot of friction because some people wanted all copies to be deleted, not just the link removed. This encryption allows for plausible deniability against deduplication. Mega can't possibly know what are all the copies of some content, so even if they comply with DMCA requests as before, nobody can force them to delete all provided copies.
