A nice bit of analysis by folks at CMU, in support of the Center for Democracy & Technology, exposes that a VPN service is apparently selling user traffic for commercial purposes.
Usually people seek a VPN in order not to have their web and mail interactions mined for profiling by operations they never heard of. It isn’t like web sites don’t track an immense amount of data that can be used for … almost anything. But at least when users visit a site they can make an informed decision about what to share. Not so with a provider like Verizon or Comcast, which can harvest your open data flows. VPNs limit that potential. Unless they’re in cahoots with advertisers and other entities too.
