I think it’s technically the same in Germany but indent doesn’t matter that much so it’s illegal even if you claim you didn’t know. Also owning it is also illegal I think. When you stream it, you don’t own it.
And honestly I don’t see the benefit of downloading it. Do I have to wait till the whole season is out or do I torrent each episode separately? Neither sounds fun. I can just click the episode I want to watch and watch it. Why bother to download it as a whole?
