My hunch is that they were indeed served with an NSL. The transparency report bullshit is an extra thing they've done to have mercy of NSA or whatever at the expense of confusing (quite) a few people (people mentioned that canary practice wasn't confirmed as illegal or legal by any court proceeding). One thing to realise is that they (AFAIR) never said they'd quit the business if they ever get served with an NSL.
