Whaaaaa?
No a vpn is NOT just about dns.
Dns is the starting point, but the main idea is to route your traffic through a central point without logs.
This means that from a network sniffing perspective, I know you’re sending data to the vpn endpoint, but the data is encrypted (also a vpn important point) and I don’t know where it’s going at all after that.
Even if I’m sniffing the traffic going out of the vpn endpoint , because there’s many people using the same point, while I can see that someone on the vpn was looking up pages on the pirate bay looking for the latest movie, I’m unable to match that to. A person connected. It could be one of thousands of people browsing with this vpn. So I don’t know that it was you looking for the latest minions movie.
They’re fed propaganda to believe that privacy doesn’t matter….
But just imagine a Google admin had access to all the information about you and wanted to blackmail you into doing something…. The sheer power of that is terrifying.
