This reminds me of a friend of mine who proxies all his web traffic through something which strips user agents and referrers. It's very easy for me to tell when he visits my website, because the logs show "-" for each of these fields.
I wonder if the best strategy, then, is to figure out a very common user agent string and use that. The EFF's Panopticlick might be a good start: https://panopticlick.eff.org.
Simply drawing attention to the fact that his attempt at anonymity acts a key personal identifier in this instance.

It is fun to think of Steve Jobs as the lone person saying "fuck you" to the NSA. But it isn't realistic. It isn't like the other companies are run by meek people who love bending over to authorities.
That's incitement enough to try to get them on board.
Why go after the myriad of handset manufacturers when you could just get the network providers on board?
