It's a report that spends most of its length telling you in some detail exactly what they can't legally tell you.
Considering how self-congratulatory HN readers are about this community's intelligence, you'd think more of them would be able to read between the lines.
A report telling me what it can't say is not precisely informative. Because I know that they can't tell me much about NSA.
Not to mention these two claims are contradictory:
"This report doesn't include national security requests."
"Unfortunately, the government allows services to disclose only the aggregate number of all law enforcement and national security requests received "
Does it include the NSA request, or not in the aggregate? First sentence says no, second implies yes.
Fact is, that's not a Transparency Report, it's PR Report, to make you feel better and not run away screaming. I've decided that Dropbox/Google Sync shouldn't be trusted for anything of any importance.
