Not only that, but you can play pirated media files on any device, with highly customizable media players, without active internet, and with community based subtitles. Most streaming service provide subtitles to only handful of languages. And you can get surround sound on a PC which is afaik still not available when you watch using official browser based players. For some of these reasons I still reach for khm khm "downloadable" content even if it's available on services I'm paying.
As is the customer support you'll receive on many private trackers - even the free ones.
