It doesn't. Here in the Netherlands, downloading was actually legal until recently, regardless of where the download was from. Uploading of copyrighted material always has been punishable. Meaning that using Torrent to get these movies is illegal whether you already own a copy or not, since you're "helping piracy".
Which is true in a way. I see that as a hearty FU to the media companies for their customer-hating tactics in hopes they will change their ways. That's how far my ethics go. That, by the way, was also the policy of Dutch lawmakers for a good while: their stance was to not make downloading illegal, or to decline to prosecute downloads of any content that isn't reasonably available for download from a legal source. (reasonably meaning: released in a timely manner, priced at or below the physical medium, allowing time shifting and offline playback). Sadly they dropped that stance and kowtow to the "intellectual property" camp.
