BC, Let me do a simple illustration.
If you and had two tin cans and a 100 meter length of string, we could have a private conversation. They would be no need to make it virtual.
But if we used megaphones instead, it would not be private at all.
An mechanism to let people communicate in a public place without others bowing might be named a VPN, in a manner of speaking. If we both spoke a minor language of Malaysia, and were the only ones, we could have a private conversation. But claiming to be anonymous would be incorrect.
Koj to taub kuv hais dab tsi ?
Do you understand what I said?
