There are many reasons!
It is used to protect yourself from hackers, as stated, and other prying eyes.
It is used to prevent your movements from being tracked.
It is also used for accessing the ‘dark web’ or for hiding various illegal activities because clearly, those people don’t want their activities to be discovered. Think of it like using money. Money is legal tender. We use it legally for doing our shopping. Criminals use it illegally to buy drugs, guns etc.
We believe that a VPN is an absolute must, especially in these times of ‘Big Brother’, where our data is appearing all over the place, and criminals are using every trick in the book to access our information, our accounts, our passwords. We need to make it as difficult as possible for them, don’t you think?
it is totally and absolutely legal to use a VPN in the UK. There is not a single UK law which would forbid or prevent you from doing so. You are well within your rights.
it is illegal to use a VPN in China, Russia, Turkey, Iraq, and the UAE among a handful of others including Iran and North Korea. Some of these countries will fine VPN users or at the very least discourage the use of VPNs by limiting their use.
When you are in the UK it is perfectly fine to watch say BBC iPlayer through a VPN, provided of course that you have a BBC licence.
Many expats watch UK TV abroad, and indeed, there are numerous sites offering this service. However, if you wish to use a VPN for this purpose, i.e., whilst living or travelling abroad it is your responsibility to keep up with the ever-changing legislation, and the complexities of the various streaming services – far too numerous for us to go through here. We basically supply a VPN service, and one of the advantages of that service is that consumers can access their TV all in one place.
