That's a good link. Thanks.
I still stand behind my statement. I used the term "free" because I didn't want to get into a whole debate over paid VPN services, which by and large aren't anonymous. We have enough of those threads here.
Regarding free VPNs, they aren't anonymous either (by and large). There's one entity running the servers, and they can compromise your identity if they want to or are compelled. Free VPNs probably offer less anonymity than paid VPNs.
JonDo is probably the closest to Tor, but the last time I checked, all the servers were in Germany. And the source code was modified a long time ago to allow law enforcement to uncover someone's identity. Some people call it a back door, and others object to that term (since they openly acknowledge it).
Tor is in a class of its own, and there's no close second.
Edit: I looked at the site you linked to again. The ratings are not well thought out. Ratings that bad make me question the site.
