I have gone through a lot of google pages explaining the finer technical points of a vpn, but none answer this question.
There's a lot of troubleshooting advice on stack, but this is not a troubleshooting question. Did get a load of info on what they actually do, but who pays for the constant tunneling of information from the users end through the vpn provider's networks after they have paid the vpn monthly costs? ie, can you cheekily browse the internet using their data?
