Canaries only make sense if the company actually cares about letting their customers know about a possible NSL. They might not be legal as it's a pretty obvious wink wink nudge nudge that they received one. Apple and Amazon are big enough that they aren't going to mess around with utopian EFF rhetoric and will do whatever is required them by the law. None of the big boys care about "don't be evil" mantras anymore. They care about what keeps the stock price up and the federal government off their ass.
