>>212908902For me it's about convenience. I want to download the shit I like onto a hard drive so I can watch it instantly whenever I want without having to hunt through streaming services, watch commercials, or deal with their horrible video playback controls.
For example, I have amazon prime, but I still download all the amazon prime shows I want to watch because I hate dealing with their streaming service.
If there was a Steam equivalent for movies I would use that. Where I physically download the video files and can do whatever I want with them.
As Gaben said, piracy is almost entirely a service problem.
