This article [1] is so stupid I want my seconds back.
The matter in question is: who do you trust more? Your ISP or the VPN provider? The default should be that you don't trust your ISP, especially if you are in the UK. Hence, trusting a VPN provider is the lesser of two evils.
Will that protect your child-pornography-viewing? If you use Qubes OS, where you have a VPN on the host, then you use Whonix in a VM, where you use tor, then you are probably safe.
Are you a terrorist planning to destroy America? You are probably our of luck, but for the truly paranoid it could be achieved.
My advice: it is better to trust VPN providers in other countries than your own, just select decently (aka, not Hide my Ass). NEVER trust your ISP!
