Plain TCP/IP traffic can be compared to a postcard: source
address, destination address and message are readable by
any public station that the traffic passes through.

Encrypted TCP/IP traffic (like SSL traffic) can be compared
to a letter: source and destination address are readable by
any public station that the traffic passes through, BUT the
message is not.

TCP/IP traffic over a VPN can be compared to a courier
shipment: /while in the hands of the VPN/, neither the
source address nor destination address nor message are
readable by any public station that the traffic passes
through. However, the VPN provider can (and must) read at
least the source and destination addresses. The VPN provider
can also read the message, if the traffic through the VPN
is not encrypted by the originating application.

So, can you trust your VPN provider to keep the addresses
secret? Can you trust your VPN provider to not peek at your
data? Is your data valuable enough to employ a commercial
VPN?
