I've been downloading the same way since way before Netflix started, that might be part of it but also, I used to have issues playing Netflix in Linux (last I tried). I also like not having to deal with their app or their app changes (I can use any video player and transfer anything on mobile if I wish). And lastly, I can keep a recording of what I liked even if it disappears from netflix.com (IE: "Netflix’s US Catalog Has Shrunk by More Than 2,500 Titles in Less Than 2.5 Years").
