I have a decent knowledge of the law, I wish I had as much knowledge about E2 machines.....
Proof is in the pudding, no person has or will ever be prosecuted (in the UK) for using a Kodi box to watch TV in their home, or even for the dreaded CShare... However, if you sell the service to others, you are open to prosecution.
In this country the law surrounding copyright and digital media cannot keep up and will not keep pace with improving technology. I can refer to Torrents and the latest laws to protect copyright. If you live in the UK and download say, Now 84 on MP3, how on earth can you be prosecuted? If you have purchased the media of Now 84, you have the legitimate rights to listen to that media, therefore having a copy to listen to at a later date is perfectly within the law. We all have done this for years by ""taping"" out vinyl abums, or transferring CD's to MP3 - each perfectly within the law.
The same applies to watching streamed media. If you watch something via an illegal stream, you may still have the legitiamte means to watch that media - i.e. you may have a valid sub via Sly or Virmin. Therefore you have the rights to watch that product - forget the means of the transporter.
The law is broken by sharing the the stream, you are no way permitted to share this service that is for the providers.
By watching - no law broken - supplying - law broken.
The same applies to the dreaded Cshare - if you have a valid sub, you can within the law share it with yourself, ie around your home, your caravan, any amount of TV within your home. This is 100% against the terms of service from providers, but not against the law. IT is against the law for you to share this service with people who have not got a valid subscription.
