Makes sense to me. If you torrent a movie, you have to find it from a decent place (otherwise it could be a completely different movie, shitty release etc) then you may need to find captions for it, if you need them. This kind of thing isn't actually easy for non-technical people. However I think it comes down to the fact: most people want to pay but shit is just so expensive otherwise.
(I'm hard of hearing and their streaming is useless to me except for foreign movies, which do get English subtitles.)
