My concern is that they are logging traffic and will retroactively enforce new laws. This is concerning for someone born in an Islamic country and having lived in China (both somewhat enemies of the UK occasionally - I don’t actually know if there is/will be discrimination). Better safe than sorry.
Until government orders ISPs to to send details of all customers who connected to known VPN services and then issue everyone a fine as a warning or worse.
The thing is, currently nothing works in the UK, so if you think you'll be able to dispute anything...
