No..streaming or watching the content is not breaking the law and its doesn't infinge copyright laws because copyrighted information is stored only temporarily on the user’s computer, and temporary copies are exempt from copyright laws.
plus its not illegal to download or own software that enables streaming..
but
it is illegal to sell a product or ad on's that enable streaming...
That is also my interpretation of what the article in the link provided by
@steve50 says.
I bought a Kodi box from
eBay and ending up dumping it, it was very poor quality. I now have an Amazon Fire box which is excellent, and although it is supposed to be possible to install Kodi onto that, I haven't done so. I have, however, installed Kodi on my desktop PC, and it works well.
Another way of streaming TV content is to just go online, it is easy but a lot of the websites seem to be loaded with adware, and Internet security software often blocks them because they are full of malware. Others get closed down following court orders, but are usually replaced by new ones.
It seems to follow that if streaming is legal because nothing is downloaded and no copies are made, and nothing distributed, streaming via your PC, laptop, mobile phone must also be legal. A lot of the streams originate from non-EU countries anyway, but the confusing part for me is that some provide streams of channels that subscription channels in the EU, such as Sky, I would have thought it illegal to watch them free of charge via a stream, but perhaps not if streaming is not an illegal activity.
