I am not defending the current situation but I am not aware of any case where anyone in the UK has gone to jail for piracy. Invariably what actually happens in such cases is:

1. See headline 'movie pirate goes to prison' which implies a link between the activity and the event 2. Actually read article based on industry press release and learn that the defendant was actually convicted for counterfeiting because they were running a business selling set-top boxes with preinstalled unauthorised streaming software or running their own third party unauthorised streaming service with paid subscriptions or something.
