Not really the point of the article, but I'll use it as a soapbox anyway: Privacy (of the sort supported by Tor) is never a technology problem - it's a government / legislative problem.
Whatever you try, whether Tor or VPNs or whatever - doesn't matter when the cops come knocking. VPNs are coming under legal attack now, and more and more sites refuse to work with them. You can say you're just running a relay, but if it came from your server they will put you in jail. Or consider the cyrpto anonymizer services - the folks running them might claim ignorance of where the crypto is coming from or going to - but they still go to jail.
If you want privacy, you have to get it at the ballot box.
