I read that to be able to browse anonymously, using only Tor is not sufficient: Your ISP can see that you are on Tor but he cannot see what pages you are visiting because of onion routing.
On the official Whonix page they affirm that their OS protects privacy more than a VPN: See the picture HERE. This seems a very adequate solution because whonix is free and opensource while nowadays there is no free VPN.
Suppose a user runs whonix inside virtualBox on a host whose wifi is public (there is no password to connect to the wifi, you should login with your personal account to access internet), I am having trouble to see how the user internet traffic is protected.
I mean even if it is encrypted by whonix, isn't it passing through the host and thus the ISP can see the user is on Tor (Tor nodes ips are public...)
Side question: Is using a private wifi (WPA protected) better or is it the same thing ?
