A VPN on Xbox, PlayStation or Switch, do we have the right or not?
Using a VPN is not prohibited black on white under the conditions of use of Microsoft, Sony or Nintendo. But as always, it all depends on what you do with it.
If it is to change the game server, modulate your ping or play with friends abroad, no problem in general. But if you use it to access content or prices reserved for another region, you get nails. In this case, the platforms could consider that you violate some of their rules, with the key to an order blocking, or even a suspension of account.
